� <br /> � <br /> General: Control soil compaction during construction providing minimum percentage of � <br /> d.ensity specif ied for each area classif ication indicated below. <br /> Percenta�e of titaximum Density Requirements: Compact soil to not less than the � <br /> following percentaRes of maximum density for soils which exhibit a well-defined <br /> moisture density relationship (cohesive soils) determined in accocdance with ASTM D <br /> 1557; and not less than the following percentaqes of relative density, determined in � <br /> accordance with ASTM D 2049, for soils which will not exhibit a well-defined moisture- <br /> density relationship (cohesionless soils). <br /> Structure, BuildinQ Slas and Steps, Pavements: Compact in 8" lifts to an average � <br /> 9896 and a minimum 9596 maximum density. <br /> Lawn or Unpaved Areas: COmpact in 8" lifts to 9096 maxiiYium density for <br /> cohesive soils. . ' <br /> Pavements: Compact in 8" lifts to an average 9596 and a minimum 9296 maximum <br /> density. , <br /> Moisture Control: Where subgrade or layer of soil material must be moisture conditioned <br /> before compaction, uniformly apply water to surface of subgrade, or layer of soil � <br /> material, to prevent free water appearing on surface during or subsequent to compaction <br /> operations. <br /> Remove and replace, o� scarify and air� dry, soil material that is too wet to permit � <br /> compaction to specified density. <br /> Soil material that has been removed because it is too wet to permit compaction ' <br /> may be stockpiled or spread and allowed to dry. Assist drying by discing, harrowing <br /> or pulverizing until moisture content is reduced to a satisfactory value. <br /> 3.03 BACKFILL AND FILL: � 1 <br /> General: Place acceptable soil material in layers to required subgrade elevations, for <br /> each area classification listed below. � <br /> In excavations, use satisfactory excavated or borrow material. • <br /> Under ttrassed areas, use satisfactory excavated or borrow material. , <br /> Under walks and pavements, use subbase material, or satisfactory excavated or <br /> borrow material, or combination of both. � <br /> Under steps, use subbase material. <br /> Under building slabs, use drainage fill material. � <br /> Under pipin� and conduit, use subbase material where subbase is indicated under <br /> piping or. conduit; shape to fit bottom 90 degrees of cylinder. � <br /> EARTHWORK 02200 - 6 <br /> � <br /> � <br />
