.. ..a <br /> OLD RIVER GOLF COURSE <br /> Page No. 9 <br /> APPENDIX A <br /> ENGINEERED FILL SPECIFICATIONS <br /> ( 1) Preliminary Operations <br /> After the cleaning and stripping operation and the cuts have <br /> been completed and before any fill is placed in any particular <br /> area, the existing surface shall be scarified to a depth of 6 <br /> inches and compacted to dry densities in excess of 90 percent <br /> of the maximum dry density as obtained by the Modified <br /> Compaction Test, ASTM D1557, designation. It may be necessary <br /> to adjust the moisture content of the subgrade soil by <br /> watering or aeration, to bring the moisture content of the <br /> soil near optimum in order that the specified densities can be <br /> obtained. <br /> (2) Source of Material <br /> Engineered fill materials (on site or import) shall consist of <br /> sandy silts, sands, or sands and gravels unless stated <br /> otherwise in the report. Engineered fill material shall not <br /> contain rocks greater than 3 inches in greatest dimension and <br /> should be nonexpansive in nature with a plasticity index less <br /> than 12. <br /> At least seven days prior to the placement of any fill, the <br /> engineer shall be notified of the source of materials and <br /> samples shall be obtained to determine the suitability of the <br /> materials and for conducting laboratory compaction test on <br /> these samples. <br /> (3 ) Placing and Compacting <br /> Fill materials shall be spread in layers and shall have a <br /> uniform moisture content that will provide the specified dry <br /> density after compaction. If necessary to obtain uniform <br /> distribution of moisture, water shall be added to each layer <br /> by sprinkling and the soil disced, harrowed, or otherwise <br /> manipulated after the water is added. The layers of the fill <br /> material shall not exceed 8 inches and each layer shall be <br /> compacted with suitable compaction equipment to provide the <br /> specified dry densities. <br /> ' t VERS h <br /> D �^ <br /> �SSOG\ <br /> r <br />
