F. All low permeability and permanent embankment fill shall be moisture conditioned to the specified <br /> range.Water required for moisture conditioning shall be applied on the fill or in the borrow areas using <br /> water trucks with spray bars for even distribution of water.Adjustments in moisture content shall be <br /> made principally in the borrow area.The moisture content of the fill materials,prior to and during <br /> compaction,shall be uniform throughout each layer of the material. Mixing of wet and dry material on <br /> the fill to obtain the proper moisture content shall not be allowed. <br /> G. All surfaces shall be finished to provide adequate drainage.Any softening or loosening due to the <br /> collection of water shall be corrected by overexcavation and replacement.The finished surface shall be <br /> reasonably smooth,compacted,free from irregular surface changes,and comparable to the <br /> smoothness obtained by bladegrader operations. <br /> H. The 1H:1V low permeability fill slope shall not be left exposed for heights greater than 5 feet. <br /> I. The low permeability and permanent embankment should be constructed simultaneously. Low <br /> permeability fill material should be"benched"into the permanent embankment material to prevent the <br /> development of a potential sliding surface. <br /> 3.6 COMPACTION REQUIREMENTS <br /> A. Compact all materials by mechanical means.Flooding or jetting will not be permitted.If compaction <br /> tests indicate that compaction or moisture content is not as specified,material placement shall be <br /> terminated and the Contractor shall take corrective action prior to continued placement. <br /> B. Place fill in loose lifts not exceeding 8 inches.Compact each lift to at least 95 percent relative <br /> compaction within moisture content of-1 to+3 percent of optimum.A kneading compactor such as a <br /> pad foot roller or equivalent is required for embankment fill compaction. Rubber tired rollers are <br /> specifically excluded. Do not attempt to compact fill material that contains excess or insufficient <br /> moisture.If the fill contains insufficient moisture,add water by sprinkling and thoroughly disking the fill. <br /> If the fill contains excess moisture,aerate the material by blading,disking,harrowing,or other methods, <br /> to accelerate the drying process. <br /> C. Compaction curves for the full range of soil materials to be used in the embankment shall be provided <br /> by the Quality Control Technician. <br /> 3.7 FIELD DENSITY AND MOISTURE TESTING <br /> A. Density and moisture testing will be carried out by the Quality Control Technician as specified herein <br /> and as specified in the Table at the end of this section to determine if adequate compaction of the <br /> embankment material is being achieved. <br /> 3.8 SITE GRADING <br /> A. Perform all earth work to the lines and grades as shown.Shape,trim,and finish slopes to conform to <br /> the lines,grades,and cross sections shown. Make slopes free of all exposed roots and stones exceeding <br /> 6-inch diameter. Finished site grading will be reviewed by the Engineer.Blend new low permeability and <br /> permanent embankment fill into existing topography. Perform grading such that ponding or channeling <br /> of water is avoided. <br /> Loloff Slurry Wall 31 23 00-5 <br />
