Plow strip, or break-up sloped <br />surfaces steeper than 1 vertical to,4 horizontal so that fill material will bond with existing <br />surface. <br /> <br />D. <br /> <br />When existing ground surface has a density less than that specified for particular area <br />classification, break up ground surface, pulverize, moisture-condition to optimum <br />moisture content, and compact to required depth and percentage of maximum density. <br /> <br />E. <br /> <br />Place backfill and fill materials in layers of 8 in. loose depth for material compacted by <br />heavy compaction equipment, and 6 in. in loose depth for material compacted by hand <br />operated tampers. <br /> <br />F. <br /> <br />Before compaction, moisten or aerate each layer as necessary to provide optimum <br />moisture content. Do not place backfill or fill material on surfaces that are muddy, frozen, <br />or contain frost or ice. <br /> <br />G. <br /> <br />Place backfill and fill materials evenly adjacent to structures, without wedging against <br />structures or displacement of piping or conduit. Compaction equipment used within 10ft. <br />of buried walls and soil supported structures shall not exceed 2000 Ibs. <br /> <br />" <br /> <br />u 3.04 GRADING <br /> <br />LJ <br /> <br />r--'"\ <br /> <br />LJ <br /> <br />n <br /> <br />u <br /> <br />r> <br /> <br />LJ <br /> <br />I' <br /> <br />L.J <br /> <br />1\ <br /> <br />LJ <br /> <br />n <br /> <br />06/05 <br /> <br />L.J <br /> <br />A. <br /> <br />General: Uniformly grade fill areas within limits of project including adjacent transition <br />areas. Smooth finished surface within specified tolerances, compact with uniform levels <br />or slopes between points where elevations are shown, or between such point and existing <br />grades. No soft spots or uncompacted areas will be allowed in the work. <br /> <br />B. <br /> <br />Grading Surface of Athletic Field Fill: Athletic field shall be sloped at 1.0% from the <br />crown to the edge ofthe field on each side, and compacted as specified. <br /> <br />c. <br /> <br />Grading Outside Athletic Field Lines: Finished grade adjacent to or outside of athletic <br />field shall be restored to original elevations. <br /> <br />D. <br /> <br />Stones or rock fragments larger than 2-1/2 inches in their greatest dimension will not be <br />permitted in the top 6-inches ofthe subgrade line of all dike, fills or embankments. <br /> <br />02200-5 <br /> <br />03-4138.8 <br />
