A.Scope: This specification shall govern for all work necessary toplace and compact all suitable materials obtained from street,storm sewer, channel, and structural excavation for utilization inthe construction of street or.roadway embankments, dikes, levees,backfill of structures and retaining walls as required to completethe project.
B.Material: Material used for embankment shall be free from muck,trees, stumps, brush, roots, rubbish, and in all ways be suitablefor embankment.
PART 2 CONSTRUCTION METHODS
2.01 PROCEDURE
A.General: Prior to placing any embankment, the surface of theground, including plowed loosened ground or surface roughened bysmall washes or otherwise, shall be restored to approximately itsoriginal slope by blading or other methods and where indicated onplans or required by the engineer, the ground surf ace thus preparedshall be compacted by sprinkling and rolling.
Where indicated on plans or directed by the engineer, the surfaceof hillsides to receive embankment shall be loosened by scarifyingor plowing to a depth of not less than 4" or cut into steps beforeembankment materials are place. The embankment shall then beplaced in layers, as hereinafter specified, beginning at the lowside in part with layers and increasing the widths as theembankment is raised. The materials which have been loosened shallbe re-compacted simultaneously with the embankment material placedat the same elevation.
Where embankments are to be placed ad jacent to or over existingroadbeds, the roadbed slopes shall be plowed or scarified to adepth of not less than 4 11 and the embankment, built up insuccessive layers, as hereinafter specified, to the level of theold roadbed before its height is increased. Then, if directed, thetop of the old roadbed shall be scarified and re-compacted with thenext layer of the new embankment. The total depth of the scarifiedand added material shall not exceed the permissible depth of layer.
Trees, stumps, roots, vegetation or other unsuitable materialsshall not be placed in embankment. Embankments shall beconstructed to the grades shown on the drawings. After completion,it shall be continuously maintained at its finished section andgrade until the project is accepted.
(
(
(
42
Except as other wise specified, earth embankments shall be constructed in successive layers for the full Widt� 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 11 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 uni form 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 11 below grade, and the material shall be mixed and reshaped by blading and then sprinkled and rolled in accordance with the requirement outlined �bove for earth embankments and to the same density as that required for the adjacent embankment.
B.· Retaining Walls, Storm sewers and Bridges: Embankments or backfillplaced adjacent to over pipes, culverts, retaining walls, stormsewers 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 11 depth of loose material, thoroughly mixed and wetted uniformly to the moisture content directed, and shall be compacted by approved methods, maintaining the required moist ure 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 11 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.

C.Density: For each layer of embankment, backfill and selectedmaterial, it is the intent of this specification to provide anapparent dry density of the minus 1/4" material of not less than98% Standard Proctor Density as prescribed by AASHO Standard methodT-99, latest revision. It is also the intent of this specificationthat the sequence of work in constructing embankments or backfillshall be such that no compacted layer will be allowed to loseeither the moisture or density specified. in case work on anypartially completed embankment or backfill is suspe nded, the top6" shall be brought to the moisture and density specified forsubgrade 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.

The material to be treatedshall then be excavated to the secondary grade (proposed bottom oflime treatment) and removed or windrowed to expose the secondarygrade.k Any wet or unstable materials below the secondary gradeshall be corrected, as directed by the engineer/ architect, byscarifying, _ adding lime and compacting until it is of uni formstab_ili ty. The excavated material shall then be spread to thedesired cross section.
C.If the contractor elects to use a cutting and pulverizing machine·that will· remove the subgrade material accurately to the secondarygrade and pulverize the material at the same time,·he will not berequired to expose the secondary grade nor windrow the material.However,. the contractor shall be required to roll the subgrade, asdirected by the engineer/architect, and correct and soft areas thatthis rolling may reveal before using the pulverizing machine. Thismethod will be permitted only where a·machine is provided whichwill insure that ·the material is cut uniformly to the proper depthand which has cutters that will plane the secondary grade to asmooth surface over the entire width of the cut. The machine ·mustgive visible indication at all times that it is cutting to -theproper depth.
3.02 APPLICATION
A.Lime -shall be spread only on the area where the first· mixingoperations can be completed during the same working day. Theapplication and mixing of lime with the soil shall be accomplishedby the methods hereinafter described as "dry placing" or "slurryplacing".
1.Dry Placing: The lime shall be spread uniformly over the topof the subgrade by an approved screw type spreader box orother approved spreading equipment. the amount of limespread shall _ be the amount required for mixing to thespecified depth which will result in the percentagedetermined in the job mix formula.
The lime shall be distributed in such a manner thatscattering by wind shall be minimal. Lime shall not beapplied when wind conditions, in the opinion of theengineer/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.

2..Slurry Placing: The lime shall be mixed with water in truckswtt:11 approved di�tributors and __ applied ___ a_s . -�--__ thin watersuspension or slurry. commercial lime slurry shall 6iapplied with a lime percentage not less than the applicablefor the grade used. The distribution of lime shall beattained by successive passes over a measured section ofsubgrade until the proper amount of lime has been spread.The amount of lime spread shall be the amount required formixing to the specified depth which will result in thepercentage determined in the job mix .formula. Thedistributor truck shall continually agitate the slurry tokeep the mixture uniform.
3.03 MIXING
A.The mixing procedure shall be the same for "dry placing" or "slurryplacing" as hereinafter described:
1.First Mixing: The full depth of the treated subgrade shallbe mixed with an approved mixing machine. Lime shall not beleft exposed for more than six (6) hours. The mixing machineshall make two coverage. Water shall be added to thesubgrade during mixing to provide a moisture content abovethe optimum moisture content of the material and to insurechemical action of the lime and subgrade. After mixing, thesubgrade shall be lightly rolled to seal the surface and helpprevent evaporation of moisture. The water content of thesubgrade mixture shall be maintained at a moisture contentabove the optimum moisture content for a minimum of 48 hoursor until the material becomes friable. During the curingperiod, the material sh�ll be sprinkled as directed. Duringthe interval of time between .application· and mixing, limethat has been exposed to the open air for 6 hours or more, orto excessive loss due to washing or blowing, will not -beaccepted for payment.
2.Final mixing: After the required curing time, the materialshall be uniformly mixed by approved methods; If the mixturecontains clods, they shall be reduced in size by blading,dicing, harrowing, scarifying or the use of other �pprovedpulverization methods so that the remainder of the · clodsshall meet the following requirements when tested dry bylaboratory 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 finalmixing. The material shall be sprinkled as necessary toprovide optimum moisture. Compaction should begin at thebottom and shall continue until the entire depth of mixtureis uniformly compacted. The entire thickness of the treatedsubgrade shall be compacted to a density of at least 95% ofmaximum density at optimum moisture, as determined by testsmade in accordance with AASHO T-187 or T-191.

The material shall be sprinkled and rolled as directed by the engineer/ arc hi tee�_. All irregula,ri ties, q�pressions ·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, thefull depth of the material shown on the plans shall becompacted to the extent necessary to remain firm and stableunder construction equipment. After each section iscompleted, tests will be made by the engineer/architect. Ifthe material fails to meet the density requirements, it shallbe reworked to meet these requirements. Throughout thisentire operation, the shape of the course shall be maintainedby blading and the surface upon completion shall be smoothand shall conform with the typical section shown on the plansand to the established lines and grades. Should thematerial, due to any reason or cause, lose the requiredstability, density and finish before the next course isplaced or the work is accepted, it shall be re-compacted andrefinished 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 andgrades in accordance with the typical sections. Thecompleted section shall then be finished by rolling, asdirected, with a pneumatic or other suitable rollersufficiently light to prevent hair ·cracking. The finishedsurface shall not vary more than 3/8" when tested with� 16'straight edge applied parallel with and at right angles tothe pavement centerline .. Any variations in excess of thistolerance shall be corrected by the contractor, at his ownexpense, in a manner satisfactory to the engineer/architect.
The completed section shall be moist cured for a minimum of7 days before fur.ther courses are added or any traffic ispermitted, unless· otherwise . directed by theengineer/architect. Subsequent courses shall be appliedwithin 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 thateach test shall represent no more than 300 sq. yds. When thebase deficiency is more than 1 /2", the contractor shallcorrect such areas in a manner satisfactory to theengineer/ architect. The contractor shall replace, at hisexpense, the base material where borings are taken for testpurposes.
