3. CONTRACTOR shall place Structural Fill materials with less than 30 percent rock <br />materials above 3/4-inch size in maximum 12-inch loose lifts, and compact to 95 <br />• percent of maximum dry density (ASTM D698). <br />4. CONTRACTOR shall condition, place and compact Structural Fill containing more <br />than 36 percent rock materials above 314-inch size(rock fill) by a method compaction <br />technique. The compaction equipment shall consist of a minimum 10-ton (static drtan <br />weight) vibratory smooth-drum compactor. The number of passes and loose lift <br />thickness shall be subject to CERTIFYING ENGINEER'S approval, at no additional <br />cost to CC&V. The method SPECIFICATIONS may be changed at any time, at the <br />discretion of CERTIFYING ENGINEER, based upon changes in material <br />characteristics, field conditions, and/or compaction equipment. <br />Maximum rock size for rock fill shall be two-thirds of the compacted lift thickness, <br />unless otherwise approved by MANAGER, DESIGN ENGINEER and <br />CERTIFYING ENGINEER. CONTRACTOR shall remove oversize materials from <br />fills at no additional cost to CC&V. <br />C. Select Structural Fil] <br />1. Select Structural Fill shall be placed for miscellaneous site grading as required by the <br />MANAGER and CERTIFYING ENGINEER. <br />2. CONTRACTOR shall condition Select Structural Fill to a moisture content that allows <br />compaction to the required density and that results in a firm, unyielding surface capable <br />of allowing the movement of vehicles and equipment over the surface without causing <br />rotting or other deleterious effects. <br />• 3.
