Plow strip, or break -up sloped surfaces steeper than 1 vertical to 4 <br />horizontal so that fill material will bond with existing surface. <br />06/06 <br />02200 -6 03- 4138.0 <br />D. <br />When existing ground surface has a density less than that specified for <br />particular area classification, break up ground surface, pulverize, <br />moisture - condition to optimum moisture content, and compact to required <br />' <br />depth and percentage of maximum density. <br />E. <br />Place backfill and fill materials in layers of 8 in. loose depth for material <br />compacted by heavy compaction equipment, and 6 in. in loose depth for <br />material compacted by hand operated tampers. <br />F. <br />Before compaction, moisten or aerate each layer as necessary to provide <br />optimum moisture content. Do not place backfill or fill material on <br />surfaces that are muddy, frozen, or contain frost or ice. <br />' <br />G. <br />Place backfill and fill materials evenly adjacent to structures without <br />, <br />wedging against structures or displacement of piping or conduit. <br />Compaction equipment used within 10 ft. of buried walls and soil <br />supported structures shall not exceed 2000 lbs. <br />3.04 GRADING <br />' <br />A. <br />General: Uniformly grade fill areas within limits of project including <br />adjacent transition areas. Smooth finished surface within specified <br />tolerances, compact with uniform levels or slopes between points where <br />elevations are shown, or between such point and existing grades. No soft <br />1 <br />spots or uncompacted areas will be allowed in the work. <br />B. <br />Grading Surface of Athletic Field Fill: Athletic field shall be sloped at 1.0% <br />from the crown to the the field <br />edge of on each side, and compacted as <br />specified. <br />C. <br />Grading Outside Athletic Field Lines: Finished grade adjacent to or <br />outside of athletic field shall be restored to original elevations. <br />' <br />D. <br />Stones or rock fragments larger than 2 -1/2 inches in their greatest <br />dimension will not be permitted in the top 6- inches of the subgrade line of <br />all dike, fills or embankments. <br />E. <br />All cut and fill slopes shall be uniformly dressed to the slope, cross section <br />and alignment shown on the Drawings, or as directed by the Engineer to <br />prevent ponding water on driveways, walkways or against structures. <br />06/06 <br />02200 -6 03- 4138.0 <br />
