specified density. Rolling <br />shall be accomplished while <br />the fill material is at the <br />specified moisture content. <br />1) Rolling of each layer shall be <br />continuous over the entire <br />area and the roller shall make <br />sufficient trips to ensure that <br />the desired density has been <br />obtained. The final surface of <br />the lot areas to receive slabs <br />on grade should be rolled to a <br />dense, smooth surface. <br />m) The outside of all fill slopes <br />shall be compacted by means <br />of sheepsfoot rollers orother <br />suitable equipment. <br />n) Compaction operations shall <br />be continued until the outer 9 <br />inches of the slope is at least <br />90 percent compacted. <br />Compacting of the slopes may <br />be progressively in increments <br />of 3 feet to 5 feet of fill height <br />as the fill is brought to grade, <br />or after the fill is brought to its <br />total height. <br />o) Field density tests shall be <br />made by the Soils Engineer of <br />the compaction of each layer <br />of fill. <br />p) Density tests shall be made <br />at intervals not to exceed 2 <br />feet of fill height provided <br />all layers are tested. <br />q) Where the sheepsfoot rollers <br />are used, the soil may be <br />disturbed to a depth of <br />several inches and density <br />readings shall be taken in <br />the compacted material <br />below the disturbed surface. <br />r) When these readings indicate <br />that the density of any layer <br />of fill or portion there is <br />Resolution No. 2020-xx <br />Page 15 of 20 <br />75D-20 <br />
