displacement of the pipe due to unequal hydrostatic pressure.
F. Unstable Trench Bottom: . When the soil encountered at the
established bedding grade is quicksand, mush, or similar unstable
material, the contractor shall proceed as follows:
All unstable soil shall be removed to a depth of 2' below bottom
of pipe for pipe 2' or more in diameter and to a depth equal to the
diameter of the pipe for pipe less than 2' in diameter. Such
excavation shall be carried at least 1" beyond the horizontal
limits of the pipe on all sides. All unstable soil so removed
shall be replaced with suitable stable material, placed in uniform
layers of suitable depth as directed by the architect and each
layer shall be wetted, if necessary, and compacted by tamping to
at least 90% Standard Proctor Density. Soil which is considered
to be of sufficient stability to sustain properly the adjacent
sections of the roadway embankment will be considered a suitable
foundation material for the sewer.
W.
G. Unyielding Trench Bottom: When the soil encountered at the
established bedding grade is ledge rock, rocky or gravelly soil,
hard pan or other unyielding material, such materials shall be
removed prior to bedding the pipe. These materials shall be
excavated for a minimum of 8" below the bottom of the pipe of 1/2"
for each foot of fill over the top of the pipe, whichever is
greater, but not more that 3/41' of the nominal diameter of the
pipe. The material removed shall be replaced with sand or other
suitable granular material.
H. Shaping Trench Bottom: The bottom of the trench shall be shaped
to support the bottom quadrant uniformly for its entire length.
Provide bell holes for bell and spigot pipe, for fittings and for
couplings. The pipe shall be bedded in a foundation of stable
earth material accurately shaped to fit the lower part of the pipe
exterior for at least 1096 of its overall height. The architect may
require use of a template necessary to secure reasonably accurate
shaping of the foundation material.
2.03 BACKFILL MATERIAL
A. Unless shown otherwise on the drawings, suitable material chosen
from the excavation shall be free of large lumps or clods which
will not readily break down under compaction. Backfill material
shall be free of vegetation or other extraneous material. Material
will be subject to approval by the engineer. In areas not under
existing or proposed pavement, the last 6" of backfill shall be
topsoil.

on the drawings, it shall be granular in nature, free of large
clods and have a plasticity index (P.I.) of less than 10.
C. Initial Backfill: Initial backfill is defined as the backfill from
the bottom of the trench to 1 ' above the top of the pipe. The
contractor shall place initial backfill in maximum 8" layers (loose
measure) and mechanically tamp it to at least 95% Standard Density
- ASTM Specification D-698. Backfill below the top of the pipe
shall be placed and compacted along the sides of the pipe equally
to prevent strain on or displacement of pipe.
D. Final Backfill:
1. General: Final backfill is defined as the backfill from 1'
above the top of the pipe to finished subgrade or ground
line. See the drawings for locations where final backfill is
mechanically tamped or water tamped. All excavations shall
be confined to within the easement or right-of-way provided.
Should the excavation extend beyond the easement or right-of-
way then said excavation shall be compacted in 6" maximum
compacted lifts to at least a 95% Standard Proctor Density -
ASTM Specifications D-698. The 95% density requirement under
streets and outside of easements is a performance
specification and the contractor may use any method to
achieve the specified results.
2. Mechanically Tamped: The contractor shall place final
backfill in maximum 8" layers (loose measure) and
mechanically tamp it to at least 95% Standard Proctor Density
- ASTM Specification D-698.
37
3. Water. Tamped: The contractor shall place final backfill to
a level of 18" below the surface of the grounds. Backfill
will be consolidated by jetting. When jetting, selected
excavated material shall be placed in layers of not more than
6' to 8' in depth and jetted until all settlement ceases.
Water jets shall be long enough to reach through the martial
being tamped. It is the intent of these specifications that
water tamping shall continue until all cavities have been

2B6 COMPACTED EMBANKMENT
PART 1 GENERAL
1.01 DESCRIPTION
A. Scope: This specification shall govern for all work necessary to
place and compact all suitable materials obtained from street,
storm sewer, channel, and structural excavation for utilization in
the construction of street or roadway embankments, dikes, levees,
backfill of structures and retaining walls as required to complete
the project.
B. Material: Material used for embankment shall be free from muck,
trees, stumps, brush, roots, rubbish, and in all ways be suitable
for embankment.
PART 2 CONSTRUCTION METHODS
2.01 PROCEDURE
A. General: Prior to placing any embankment, the surface of the
ground, including plowed loosened ground or surface roughened by
small washes or otherwise, shall be restored to approximately its
original slope by blading or other methods and where indicated on
plans or required by the engineer, the ground surface thus prepared
shall be compacted by sprinkling and rolling.
Where indicated on plans or directed by the engineer, the surface
of hillsides to receive embankment shall be loosened by scarifying
or plowing to a depth of not less than 4" or cut into steps before
embankment materials are place. The embankment shall then be
placed in layers, 'as hereinafter specified, beginning at the low
side in part with layers and increasing the widths as the
embankment is raised. The materials which have been loosened shall
be re -compacted simultaneously with the embankment material placed
at the same elevation.
Where embankments are to be placed adjacent to or over existing
roadbeds, the roadbed slopes shall be plowed or scarified to a
depth of not less than 4" and the embankment, built up in
successive layers, as hereinafter specified, to the level of the
old roadbed before its height is increased. Then, if directed, the
top of the old roadbed shall be scarified and re -compacted with the
next layer of the new embankment. The total depth of the scarified
and added material shall not exceed the permissible depth of layer.
Trees, stumps, roots, vegetation or other unsuitable materials
shall not be placed in embankment. Embankments shall be
constructed to the grades shown on the drawings. After completion,
it shall be continuously maintained at its finished section and
grade until the project is accepted.
42
Except as other wise specified, earth embankments shall be
constructed in successive layers for the full width of the cross
section and in such lengths as are suited to the sprinkling and
compaction methods utilized. Prior to compaction, the layers shall
not exceed 6" in depth. Layers of embankment may be formed by
utilizing equipment which will spread the material as it is dumped,
or they may be formed by being spread by blading or other
acceptable methods from piles of windows dumped from excavating or
hauling equipment in such amounts that material is evenly
distributed.
Each layer of embankment shall be uniform as to material, density
and moisture content before beginning compaction. Where nonuniform
layers abut each other, each layer shall be feather edged for at
least 100' or the material shall be so mixed as to prevent abrupt
changes in the soil. No material placed in the embankment by
dumping in a pile or windrow shall be incorporated in a layer in
that position, but all such piles or windrows shall be broken and
embankment material mixed by blading, harrowing or similar methods
to the end that a uniform material or uniform density is secured
in each layer.
Water required for sprinkling to bring the material to the moisture
content necessary for maximum compaction shall be evenly applied,
and it shall be the responsibility of the contractor to secure a
uniform moisture content through the layer by such methods as may
be necessary. In order to facilitate uniform wetting of the
embankment material, the contractor may apply water at the material
source. Such procedure shall be subject to the approval of the
engineer. Each layer of embankment shall be compacted by approved
power drawn rollers to the density specified.
All earth cuts, full width or part width cuts in side hill, which
are not required to be excavated below subgrade elevation for base
and backfilled, shall be scarified to a uniform depth of at least
6" below grade, and the material shall be mixed and reshaped by
blading and then sprinkled and rolled in accordance with the
requirement outlined above for earth embankments and to the same
density as that required for the adjacent embankment.
B. Retaining Walls, Storm Sewers and Bridges: Embankments or backf ill
placed adjacent to over pipes, culverts, retaining walls, storm
sewers and bridges shall be of suitable material and shall be
placed in successive layers approximately parallel to the finished
grade. Special care shall be taken to prevent any wedging action
against the structure. For such distances along embankments
adjacent to structures where it is impractical to employ the
compaction methods specified, the embankment material shall be
placed in layers not exceeding 6" depth of loose material,
thoroughly mixed and wetted uniformly to the moisture content
directed, and shall be compacted by approved methods, maintaining
the required moisture content by adding sprinkling, necessary until
each layer has been uniformly compacted to the density specified.
Embankments placed around spill through type abutments shall be
constructed in 6" loose layers of uniform suitable material placed
in such a manner as to maintain approximately the same elevation
on each side of the abutment, and all materials shall be mixed,
wetted and compacted as specified above.
43
C. Density: For each layer of embankment, backfill and selected
material, it is the intent of this specification to provide an
apparent dry density of the minus 1/4" material of not less than
98% Standard Proctor Density as prescribed by AASHO Standard method
T-99, latest revision. It is also the intent of this specification
that the sequence of work in constructing embankments or backfill
shall be such that no compacted layer will be allowed to lose
either the moisture or density specified. in case work on any
partially completed embankment or backfill is suspended, the top
6" shall be brought to the moisture and density specified for
subgrade before placing the next layer of embankment or backfill.
After each layer of earth embankment or select material is
completed, tests as necessary will be made. If the materials fail
to meet the density specified, it shall be reworked as necessary
to obtain that density. The moisture content and density shall be
maintained so as to pass the above compaction test until the base
material is placed.

2D LIME STABILIZATION OF SUBGRADE
PART 1 GENERAL
1.01 DESCRIPTION
A. This item shall consist of constructing one (1) or more courses of
a mixture of soil, lime and water in accordance with this
specification and in conformity with the lines, grades, and typical
sections indicated on plans or established by the engineer.
PART 2 PRODUCTS
2.01 MATERIALS
A. Hydrated Line: Hydrated lime shall conform to the requirements of
AASHO 216, Type 1, Grade A.
B. Lime Slurry: Lime slurry shall be a pumpable suspension of solids
in water. The solids portion of the mixture shall consist
principally of hydrated lime of a quality and fineness sufficient
to meet the following requirements:
1. Chemical Composition: The "solids" content of the lime
slurry shall consist of a minimum of 70%, by weight, of
calcium and magnesium oxides.
2. Residue: The percent by weight of residue retained in the
"solids" content of lime slurry shall conform to the
following requirements:
Retained on No. 6 Sieve Max 0.0%
Retained on No. 10 Sieve Max 1.0%
Retained on No. 30 Sieve Max 2.5%
3. Grade: Lime slurry shall conform to one of the following two
(2) grades:
Grade 1: The "dry solids content" shall be at least 31%, by
weight, of the slurry.
Grade 2: The "dry solids content" shall be at least 35%, by
weight, of the slurry.
C. Water: Water used for mixing or curing shall be of potable
quality.
2.02 EQUIPMENT
A. The equipment required shall include all equipment necessary to
complete this item such as grading and scarifying equipment, a
spreader for the lime or lime slurry, mixing or pulverizing
equipment, sheepsfoot and pneumatic or vibrating rollers,
sprinkling equipment, trucks and truck scales. All machinery,
tools and equipment shall be on the site and approved by the
engineer/architect prior to the beginning of construction
operations and shall be maintained in a satisfactory working
condition throughout the construction period.
PART 3 CONSTRUCTION
3.01 INSTALLATION
A. It is the primary requirement of this specification to secure a
completed subgrade containing uniform lime mixture, free from loose
or segregated areas, of uniform density and moisture content, well
bound for its full depth and with a smooth surface suitable for
placing subsequent courses. It shall be the responsibility of the
contractor to regulate the sequence of his work, to use the proper
amount of lime, maintain the work and rework the courses as
necessary to meet the above requirements.
B. Prior to beginning any lime treatment the subgrade shall be
constructed and brought to grade and shaped to conform to the
typical sections, lines and grades as shown on the plans or as
established by the engineer/ architect. The material to be treated
shall then be excavated to the secondary grade (proposed bottom of
lime treatment) and removed or windrowed to expose the secondary
grade.k Any wet or unstable materials below the secondary grade
shall be corrected, as directed by the engineer/architect, by
scarifying, adding lime and compacting until it is of uniform
stability. The excavated material shall then be spread to the
desired cross section.
C. If the contractor elects to use a cutting and pulverizing machine
that will. remove the subgrade material accurately to the secondary
grade and pulverize the material at the same time, he will not be
required to expose the secondary grade nor windrow the material.
However, the contractor shall be required to roll the subgrade, as
directed by the engineer/architect, and correct and soft areas that
this rolling may reveal before using the pulverizing machine. This
method will be permitted only where a'machine is provided which
will insure that the material is cut uniformly to the proper depth
and which has cutters that will plane the secondary grade to a
smooth surface over the entire width of the cut. The machine must
give visible indication at all times that it is, cutting to -the
proper depth.
3.02 APPLICATION
A. Lime shall be spread only on the area where the first mixing
operations can be completed during the same working day. The
application and mixing of lime with the soil shall be accomplished
by the methods hereinafter described as "dry placing" or "slurry
placing".
1. Dry Placing: The lime shall be spread uniformly over the top
of the subgrade by an approved screw type spreader box or
other approved spreading equipment. the amount of lime
spread shall be the amount required for mixing to the
specified depth which will result in the percentage
determined in the job mix formula.
The lime shall be distributed in such a manner that
scattering by wind shall be minimal. Lime shall not be
applied when wind conditions, in the opinion of the
engineer/architect, are detrimental to a proper application.
a motor grader shall not be used to spread the lime. The
material shall be sprinkled, as directed by the
engineer/architect, until the time moisture content has been
reached.
53
2. Slurry Placing: The lime shall be mixed with water in trucks
with approved distributors and applied as a thin water
suspension or slurry. commercial lime slurry shall be
applied with a lime percentage not less than the applicable
for the grade used. The distribution of lime shall be
attained by successive passes over a measured section of
subgrade until the proper amount of lime has been spread.
The amount of lime spread shall be the amount required for
mixing to the specified depth which will result in the
percentage determined in the job mix formula. The
distributor truck shall continually agitate the slurry to
keep the mixture uniform.
3.03 MIXING
A. The mixing procedure shall be the same for "dry placing" or "slurry
placing" as hereinafter described:
1. First Mixing.: The full depth of the treated subgrade shall
be mixed with an approved mixing machine. Lime shall not be
left exposed for more than six (6) hours. The mixing machine
shall make two coverage. Water shall be added to the
subgrade during mixing to provide a moisture content above
the optimum moisture content of the material and to insure
chemical action of the lime and subgrade. After mixing, the
subgrade shall be lightly rolled to seal the surface and help
prevent evaporation of moisture. The water content of the
subgrade mixture shall be maintained at a moisture content
above the optimum moisture content for a minimum of 48 hours
or until the material becomes friable. During the curing
period, the material shall be sprinkled as directed. During
the interval of time between .application and mixing, lime
that has been exposed to the open air for 6 hours or more, or
to excessive loss due to washing or blowing, will not -be
accepted for payment.
2. Final mixing: After the required curing time, the material
shall be uniformly mixed by approved methods. If the mixture
contains clods, they shall be reduced in size by blading,
dicing, harrowing, scarifying or the use of other approved
pulverization methods so that the remainder of the clods
shall meet the following requirements when tested dry by
laboratory sieves:
Minimum of clods passing 1-1/2" sieve 100%
Minimum of clods passing NO. 4 sieve 60%
3.04 COMPACTION
A. Compaction of the mixture shall begin immediately after final
mixing. The material shall be sprinkled as necessary to
provide optimum moisture. Compaction should begin at the
bottom and shall continue until the entire depth of mixture
is uniformly compacted. The entire thickness of the treated
subgrade shall be compacted to a density of at least 95% of
maximum density at optimum moisture, as determined by tests
made in accordance with AASHO T-187 or T-191.
54
8. The material shall be sprinkled and rolled as directed by the
engineer/architect... All irregularities, depressions'or..weak
spots which develop shall be corrected immediately by
scarifying the areas affected, adding or removing material as
required and reshaping and re -compacting by sprinkling and
rolling. The surface of the course shall be maintained in a
smooth condition, free from undulations and ruts, until other
work is placed thereon or the work is accepted.
C. In addition to the requirements specified for density, the
full depth of the material shown on the plans shall be
compacted to the extent necessary to remain firm and stable
under construction equipment. After each section is
completed, tests will be made by the engineer/architect. If
the material fails to meet the density requirements, it shall
be reworked to meet these requirements. Throughout this
entire operation, the shape of the course shall be maintained
by blading and the surface upon completion shall be smooth
and shall conform with the typical section shown on the plans
and to the established lines and grades. Should the
material, due to any reason or cause, lose the required
stability, density and finish before the next course is
placed or the work is accepted, it shall be re -compacted and
refinished at the sole expense of the contractor.
3.05 FINISHING & CURING
A. After the final layer or course of lime treated subgrade has
been compacted, it shall be brought to the required lines and
grades in accordance with the typical sections. The
completed section shall then be finished by rolling, as
directed, with a pneumatic or other suitable roller
sufficiently light to prevent hair cracking. The finished
surface shall not vary more than 3/6" when tested with "a 16'
straight edge applied parallel with and at right angles to
the pavement centerline. Any variations in excess of this
tolerance shall be corrected by the contractor, at his own
expense, in a manner satisfactory to the engineer/ architect.
The completed section shall be moist cured for a minimum of
7 days before further courses are added or any traffic is
permitted, unless otherwise directed by the
engineer/architect. Subsequent courses shall be applied
within 14 days after final mixing is completed.
3.06 THICKNESS
A. The thickness of the lime treated subgrade shall be-
-determined by depth tests or cores taken at intervals so that
each test shall represent no more than 300 sq. yds. When the
base deficiency is more than 1/2", the contractor shall
correct such areas in a manner satisfactory to the
engineer/architect. The contractor shall replace, at his
expense, the base material where borings are taken for test
purposes.
55
3.07 MAINTENANCE
A. The contractor shall maintain, at his own expense, the entire
lime treated subgrade in good condition from the start of
work until all the work has been completed, cured and
accepted by the engineer/architect.
3.08 METHOD OF PAYMENT
A. The yardage of lime treated subgrade to be paid for shall be
the number of square yards completed and accepted.
1. Payment shall be made at the contract unit price per
square yard for the lime treated subgrade of the
thickness specified. The price shall be full
compensation for furnishing all material, except the
lime and for all preparation, delivering, placing and
mixing these materials and all labor, equipment, tools,

PART 3 EXECUTION
3.01 INSTALLATION
A. Foundation and Installation
A competent base is an essential prerequisite to the
satisfactory performance of a Uni-stone pavement. Base design
must satisfy local or regional government or municipal
specifications for road, street, parking and pedestrian
pavements. Implicit within such design parameters is concern
for differing soil and drainage conditions, the end use of the
pavement and the availability of suitable base material.
72
1. Unsuitable, unstable or unconsolidated subgrade material
shall be excavated according to the direction of the
Architect and compacted. Backfill with 50 mm/2" to 300
.-mm/12" or as otherwise directed by the above -noted --Site
Authorities with compacted, dense, graded aggregate.
2. Place bedding course of sharp, normal weight sand* to a
uniform depth of 35 mm/1 -1 /2" levelled to the grade and
profile required. *Particle sizes: 0 to 3 mm/1 /8" with 30%
of 3 mm/1/81'.
3. Install Uni-stone units with joints not exceeding 3
mm/1/8"
4. Where required, cut paving stones with an approved cutter
to fit accurately, neatly and without damaged edges.
5. Tamp paving stones with mechanical vibrator uniformly
level, true to grade and free of movement.
6. Fill voids in joints by sweeping in sand using the same
material as described for the bedding course.
B, Labor
For estimating labor costs, applicators will find that unskilled
labor will master installation techniques within a matter of
hours; one man hour should result in the laying of 2m2 to 3m2
(20 to 30 sq. ft.) (including screening sand; laying Uni-stone;
tamping into place; sweeping dry sharp sand into joints).
This estimate of time does not include preparation of the sub-
base.
Site supervision is available to instruct and train crews who
require initial installation experience.
C. Laying instructions
The herringbone pattern is recommended as it provides the best
possible lock effect, for all applications.
1. HERRINGBONE PATTERN: Begin in a corner. After the 8th
stone, you may continue at an angle of 450 following the
numbered laying sequence indicated.
2. RUNNER PATTERN: Important: rows of stones should be at
right angles to the driving direction.
3. PARQUET PATTERN: Standard stones are laid in pairs in such
a way that double rows develop. Traffic direction is not
important in this case.'
D. Paver Completion - Backfill to paver edging; clean-up premises
and remove all debris resulting from this installation.

PART 3 EXECUTION
3.01 PROCEDURE
A. General; The contractor shall have the option of mixing the
concrete on the site or procuring concrete from a "transit
mixed" concrete plant. Aggregates shall be proportioned by
weight unless a satisfactory volumetric method of measurement is
proportioned by weight. Water shall be measured by an accurate
measuring device which can be adjusted to compensate for
variations in the free moisture content of the aggregate.
The concrete shall be mixed in quantities required for immediate
use and any concrete which is not in place within one (1) hour
after start to mixing shall not be used unless otherwise
authorized 'by opinion of the architect or engineer. In
threatening weather, which in the opinion of the engineer nay
result in conditions that will adversely affect the quality of
the concrete to be placed, the engineer may order postponement
of the work.
Where work has been started and changes in weather conditions
require protective measures to be used, the contractor shall
furnish adequate shelter to protect the concrete against damage
from rainfall or damage due to freezing temperatures. In case
it is necessary to continue mixing operations during rainfall,
the contractor shall provide protective covering for the
material stock piles as well as for the concrete being placed.
The covering for aggregate stock poles will be required only to
the extent as may be necessary to control the moisture
conditions in the aggregate so that adequate control of the
consistency of the concrete may be maintained.
84
No concrete shall be mixed without the approval of the
architect/engineer when the air temperature is at or below 400
F (taken in the shade away from artificial heat) ' *and falling.
If authorized for concrete placement during cold weather, the
concrete will be placed in accordance with the PCA "Design and
Control of Concrete Mixtures".
The maximum temperature of cast -in -place concrete (Type I,
portland cement and Type K, shrinkage compensating cement) shall
not exceed 980 F. If adjustments of the mixture for temperature
control are required, then the procedure for hot weather mixing,
placing and curing shall be in accordance with ACI 305
"Recommended Practice for Hot Weather Concreting".
B. Job Mixed Concrete: The aggregate shall be stockpiled
separately and handled in such a manner as to prevent the
inclusion of any foreign materials. Except for. emergency hand
mixing under approved conditions, all concrete shall be machine
mixed in an approved type mixer for a minimum period of 1-1/2
minutes in a drum rotating at a peripheral speed of 200' per
minute with an increase of 15 seconds for each one-half cubic
yard over one cubic yard of capacity of the mixer.
C. Transit Mixed Concrete: The mixing and the transporting
operations shall conform with ASTM Specification C-94. Mixing
water shall not be added after a truck has left the plant except
by permission of the architect/engineer or his representative.
No concrete shall be used in the work which has been held longer
than one (1) hour in a mixer truck unless approved by the
architect/engineer. If dry batched on the job site, the
batching plant operations shall conform with ASTM Specification
C-94. Transportation of the dry materials shall be performed in
such a manner as to prevent loss, aggregation or contamination
of ingredients.
3.02 COMPLIANCE
A. Laboratory Testing of Concrete: Moisture content checks will be
made at sufficient intervals to maintain accurate batching and
proportioning. All samples will be done in accordance with ASTM
sampling and testing procedures.
A set of test cylinders shall consist of three (3) test
cylinders. One (1) cylinder shall be tested for strength at
the age of seven (7) days, one (1 ) cylinder at the age of
twenty-eight (28) days and one (1) cylinder shall be held in
reserve to be tested for strength when directed by the
architect/ engineer. The cylinders shall be made and cured in
conformance with ASTM Specification C-192. Curing facilities
shall be provided in accordance with ASTM C-31. Cylinders
shall be tested in conformance with ASTM C-39.
B. Failure to Meet Strength Requirements: Should the strength
shown by the test specimens made and tested fall below the
values required, the architect/engineer shall have the right to
require changes in proportions or to require additional curing
on those portions of the structure represented by the test
specimen which failed. If additional curing does not give the
strength required, then remove and replace those portions which
fail to develop the specified strength.
ME
Specimens will be considered to have failed when average
strength. for any_. period of placing is less than values
indicated in the following tables:
No. Days Consecutive
Placing of Any One Percent of
Class of Concrete Strength Specified
1 85
2 95
3 95
5 or more 100
When additional curing of portions of the structure is
ordered by the architect/engineer, it shall be done at
contractor's expense and not claim for extra compensation for
such additional curing shall be allowed. In no case shall
the contractor be required to provide such additional curing
beyond a total of twenty-one (21) days, except where average
strengths of specimens representing concrete placed on any
three (3) consecutive days, fall below 80% of the value
specified in paragraph 2.01 G. In this case, curing shall be
contained until cores drilled from portions of the structure
involved show an average strength equal to that specified in
paragraph 2.01 G. Cores shall have diameter of approximately
three (3) times the. maximum size of aggregate and shall be
tested in accordance with ASTM Specification C-42.
C. Storage of Materials:. Cement shall be stored off the ground in
a well ventilated weatherproof building. Aggregate shall be
stored in a manner that will prevent the mixing of foreign
materials and in such a manner as to prevent segregation of the.
aggregate.
D. Measurement of Materials: The measurement of materials, except
water used in the batches of concrete shall be by weight. The
different grades of aggregate shall be weighed separately.
Cement may be measured by the bag. Water may be measured by
volume. Allowance will be made for water content where moist
aggregates are used.

joint by means of copper wire No. 12B and 12C gauge or heavier
or copper nails of approved size. Concrete sections are to be
completely separated by open joint or by joint material.
D. Construction Joints
1. General: "Construction Joint" is defined as a contact
surface between plastic concrete and concrete that has
attained initial et. "Monolithic" means concrete placed
without construction joints. Waterstops shall be provided
in all construction joints in structures containing liquids
up to a point 1' above the maximum water surface elevations
nd in.all construction joints in structures with walls
adjacent to soil, below a point 1' above the finished
grade. The contractor shall obtain written authorization
of the engineer/architect to permit construction joints
other than those indicated. Where such authorization is
obtained, make additional construction joints with details
and waterstops equivalent to those shown for similar
joints.
3E:3
2. Construction: The contractor shall leave surfaces rough
—with aggregate prior to placing of new concrete.
Immediately prior to placing concrete on horizontal joint
surfaces, slush surface with mortar coating. Mortar is to
consist of regular to concrete mix less coarse aggregate.
One vertical surface, mortar is to be brushed on and worked
into irregularities on surface. Keyways are to be formed
so as to permit easy removal of forms without imaging the
concrete. Waterstops are to extend into both old and new
pour an equal distance or according to manufacturer's
recommendations as approved by the engineer/architect.
E. Concrete Form Work: See Section 3A Concrete Form Work.
F. Placing Reinforcement: See Section 3B Concrete Reinforcement
Seal Slabs: Seal slabs will be placed in all excavations for
structures which require reinforcing steel in base slab..
Excavate 2" minimum below bottom of structural slab and pour
seal slab concrete slab bottom elevation. Rough float finish
seal slab. No direct payment will be made for seal slab
concrete.
G. Authorization to Place Concrete: The contractor. shall notify
the architect/engineer at least 24 hours in advance of a
scheduled concrete placement. The contractor shall not begin
mixing concrete (or place an order for concrete) until the
architect/ engineer has inspected the forms, reinforcing steel
and given his approval. Before concrete is placed, all embedded
items shall be accurately and securely fastened in place. The
contractor shall not place any concrete until he has at least 2
mechanical vibrators or an approved type on the project site
that are in good operating order,
H. Scheduling of Concrete Placement: The contractor shall schedule
the concrete placement so as to ensure completion during the
hours of daylight. If it is necessary to continue pouring
during hours of darkness, light the site in such a manner as to
ensure competent and safe operation. The engineer/architect can
order postponement of placing operations when impending weather
conditions threaten to impair the quality of the finished work.
Should rainfall occur after placing operations have started,
provide covering to protect work. If conditions occur which
would be detrimental to placement and setting of concrete such
as pile driving or other vibration, stop the cause of such
condition when concrete is being placed and until concrete has
age (12) hours.
I. Handling and Transporting Concrete: The contractor shall use
metal lined chutes, troughs and/or pipes in placing concrete to
prevent separation of concrete ingredients. When pouring down
steep slopes chutes will be equipped with baffles to reverse
lateral direction of movement. Downpipe will be provided at end
of chute. A maximum slope of (1) vertical to (2) horizontals
will be used. Chutes and toughs will be kept free from coatings
or hardened concrete or other harmful material. Chutes in
excess of 35' in length may be used by authorization of the
engineer/ architect only. Pumping of concrete may be done by
authorization of engineer/architect only.
3.02 INSTALLATION
A. Placing Concrete: Free fall of concrete will be limited to 43.
The contractor shall place concrete in walls and other
inaccessible places by use of tremies. Concrete will be placed
as close as possible to its final location. Vibrators will not
be used to work concrete along the forms. Concrete, reinforcing
steel or forms will not be jarred, moved or otherwise disturbed
after concrete has taken initial set. Concrete will be placed
in continuous horizontal layers approximately 12" thick. Each
successive layer will be placed while the layer below is still
plastic. If excessive water forms on the surface of concrete,
use concrete to a point approximately 1' below finish elevation
and allow to settle. To avoid cold joint, resume placement of
concrete after partial stiffening. Re -tempering of concrete or
mortar which has partially hardened will not be permitted.
B. Consolidating Concrete: Consolidation of concrete will be done
by means of spading implements and mechanical vibrators of
approved type. Use of vibrators of the type which operate by
attachment to forms will be by authorization of the
engineer/ architect only. Vibration of concrete will begin
immediately after placement and'will go completely through to
next layers below to insure mixture of both layers. Vibration
will not be used for flowing concrete laterally.
C. Placing Concrete on Ground: The contractor shall prepare the
subgrade in accordance with the applicable earthwork
specifications. Apply membrane waterproofing if called for on
the drawings and/or specifications elsewhere. If membrane
waterproofing is not required, moisten subgrade just prior to
lacing concrete, to decrease absorption of moisture from the
concrete. If necessary, pump or bail during placing operations
from suitable slump located outside of forms. Pumping will be
continued until concrete has attained initial set. Side forms
may be omitted when authorized by the engineer.
D. Placing Concrete in Water: The contractor shall place concrete
in water only by specific authorization of the
engineer/architect. Concrete placed in or under water will
contain a minimum of 6-1/2 sacks of cement per cubic yards of
concrete. The contractor shall insure that there is no movement
or flow of water in which concrete is being placed for at least
36 hours after placement. Do not disturb concrete after
placement and maintain approximately horizontal surfaces at all
times. Placement will be by use of watertight tremies of a
maximum of 10" in diameter. When concrete is placed in tremies,
raise tremie slightly, but not out of concrete until batch
discharges to bottom of hopper. Stop flow by lowering tremie.
Placement will be continuous.
E. Curing Concrete
1. General: The contractor shall have the option of using
curing compound or cotton mats with the exception of the
following:
Membrane curing compound will not be used on surfaces to be
rubbed, painted or to which waterproofing material or
liquid floor hardener is to be applied. Membrane curing
compound will not be used on concrete which may have
additional concrete placed on it later. Membrane curing
will be used for curing surfaces which cannot be
satisf actorily_cured with mats. Curing mats will be kept
moist and in contact with concrete for (7) consecutive
days. High early strength concrete will be cured for (3)
consecutive days.
2. Use of Membrane Curing Compound: Membrane curing compound
will be delivered on job site in original containers,
labeled to show name of compound, manufacturer and batch
number. Compound will b kept thoroughly mixed ad sprayed
on the structure using pressure tank type spraying
equipment. The contractor shall apply curing compound to
the concrete immediately upon removing forms at a rate of
(1) gallon per 200 sq. ft. Apply compound to slabs or
other exposed surfaces immediately after finishing or after
excess moisture has disappeared. Membrane will be kept
intact and protected from abrasive action for (14) days to
obtain equivalent to (7) days moist curing. Protect
against traffic and apply protective coating no sooner than
(24) hours after application of membrane. Damage to
membrane during (14) day period will be repaired
immediately.
F. Removal of Forms and Falsework: See Section 3A Concrete Form
Work.
G. Defective Work: All work which is deemed by the
engineer/ architect to be defective will be repaired immediately
by the contractor in accordance with the engineer/ architect
instructions.
3.03 FINISHING
A. Monolithic Slab Finish: Unless otherwise specified, slabs,
platforms and steps will be finished monolithically. Unless
otherwise specified, slabs will be level. The contractor shall
place screeds accurately and rigidly prior to placement of
concrete. Concrete will be tamped to force coarse aggregate
away from surface, then float finish and trowel to finish
building floors. "Dusting" of floor surfaces with dry materials
will not be permitted. Edges of all expansion joints will be
rounded at all expansion joints with suitable jointing or edging
tool.
B. Concrete Floor Topping and Finish: Where specified, concrete
floor topping shall be applied by the contractor to structural
slabs after equipment has been set. Toping will be placed with
engineer's/architect's authorization. Structural slab will be
broomed to expose aggregate when concrete is green. Structural
slab will b cleaned and kept moist (12) hours prior to placing
topping. Immediately before placing concrete topping, boom in
slush coat of cement and water mixed to consistency of thick
paint. Use (1) part Portland cement, (1) part sand, and (1-1/2)
parts pea gravel for concrete topping. Use no more than (5)
gallons of water per sack of cement. Add (5) pounds of non
shrinking grout aggregate per sack of cement in mix. Steel
trowel finish will be provided. If specified, the contractor
shall apply liquid floor hardener in accordance with the
manufacturer's recommendations. If specified, the contractor
shall apply integral concrete coloring in accordance with
manufacturer's recommendations.
91
C. Filling for Tie and Bolt Holes: The contractor shall fill holes
solid with cement mortar. Add white cement to mortar so that
patches will not appear darker than adjacent concrete surface.
Mortar will be placed into holes as dry as possible. Holes
passing entirely through concrete will be filled from inside of
structure with pressure gun or other devise that will force
mortar through to outside face. Strike off excess mortar flush
with surface and finish to make hole as inconspicuous as
possible.
D. Patching: Slight honey comb and other minor defects in concrete
surfaces will be patched with cement mortar mixed (1) part
cement in (2) parts fine aggregate. The contractor shall repair
by cutting out unsatisfactory material and replacing it with new
concrete, securely keyed and bonded to old concrete and finish
so as to make joints as inconspicuous as possible. Mixture will
be as stiff and dry as possible. For hydraulic structures,
repair areas in which honey comb occurs sufficiently to cause
leakage through concrete, using mortar to which non shrinking
grout aggregate has been added at the rate of (5) pounds per
sack of cement.
E. Rub Finish Surfaces:
1. Extent Required: Exposed vertical and battered surfaces
will be rub finished from 6" below surface or from blow
water level to the top, except for small structures which
extend 12" or less above finished grade.
2. Procedure: The contractor shall start the rubbing
operations immediately after from removal. Do necessary
pointing a forms are removed. Remove forms only as rubbing
progresses in No. 16 cororundum stone or equal. Rub
sufficiently to bring to surface paste and to produce
smooth dense surface without irregularities. Add no cement
to form surface paste. Spread or brush material which has
been ground to paste uniformly over surface ad allow to
take reset. Do not rub chamfered corners in first surface
rubbing. First rubbing.will be completed within 36 hours
after completion of concrete placement. In preparation for
final finish, rub with No. 30 carborundum stone or equal.
After rubbing, strip surface with brush and allow mortar on
surface to take reset, then wash surface with clean water.
Leave structure with clean, neat and uniform appearing
finish.
F. Rough Finish: For concrete having no special finish indicated,
remove ties, fill holes and remove fins and rough edges.
G. Waterstops: Waterstop material will be completely embedded in
concrete and shall extend an equal distance into both the old
and the new concrete. Waterstops will be continuous. Splices
will be made in accordance with manufacturer's recommendations
and approved by the engineer/architect.
H. Grouting
1. Mixture: The contractor shall mix grout (proportion by
weight) as follows.
92
For Setting new equipment - Where clearance is 1" or less
in thickness, the contractor shall use__(1) part Portland
cement, (1) part clean sharp. sand and (7/10) part non
shrinking grout aggregate. No more than.(5-1/2) gallons of
water per sack of cement. Where clearance is over 1" in
thickness, the contractor shall use (1) part Portland
cement, (1) part clean sharp sand, (1-1/2) parts 1/4" pea
gravel and (7/10) part non shrinking grout aggregate. No
more than (6) gallons of water per sack of cement.
Other - For general purpose grouting, the contractor shall
use (1) part Portland cement and (2) parts sand. When
space to be grouted is less than 1" and it is impossible to
tamp grout, use (1) to (1) mixture. Use stiff mixture for
grout to be tamped. To obtain stiff grout mix mortar using
amount of water required to thoroughly mix ingredients,
then continue mixing without additional water until grout
is stiff enough to be compacted by tamping when placed.
For grouting blockouts for embedded pipes and similar
items, use grout to which (5) pounds of non shrinking grout
aggregate per sack of .cement has been added.
2. Procedure for Grouting Equipment: The surfaces of
foundations that are to receive grout will be free of all
laitance, grease, oil, organic matter and loose particles.
Bolt holes will be cleaned of extraneous matter. Concrete
will be chipped in order to obtain a firmer bond as
directed by the engineer/architect. Forms for the grout
will be set true, level and tight and shall be well braced.
All equipment to be grouted shall be assembled at the
grouting site .before grouting operations begin. Base
plates and items to be embedded shall be cleaned and set in
their final positions prior to the start of grouting
operations. All equipment shall be so shimmed as. to
facilitate the removal of the shims. Shims shall be
removed only after the grout has attained -its full
strength. The areas to receive grout shall be kept wet- for
a minimum of (12) hours prior to grouting. Neat cement
mortar slush coat shall be applied with a stiff brush and
shall be scrubbed into the concrete foundation and applied
to the sides and bottom of the base plateorother item to
be set. The mortar shall be thoroughly mixed. and an excess
of water in the mixture shall be avoided. The grout shall
be continuously worked and rodded while it is being placed
in the forms. All grout containing non shrinkage grout
aggregate shall be cut off vertically below the outside
edge of the base plate or the base of the embedded
equipment and normal cement mortar shall be used in to
cover the edge of the grout. All exposed surfaces of the
grout shall be steel troweled. All exposed areas shall be
protected against rapid drying out. Items embedded in
grout shall not be stressed. The machinery embedded in the
grout shall not be operated for 36 hours.
