The results of a compaction test are given below (Mold Volume=1/30 ft³). (a) Draw Compaction Curve, and determine the maximum dry unit weight and optimum water content (b) Draw S=100%, S-90% and S= 80% curves (assume Gs=2.75) Trial no. 1 2 3 4 56 6 Weight of moist soil in the mold (lb) 3.7 4.15 4.69 4.62 4.02 3.63 Moisture content (%) 8.6 10.6 12.5 14.9 16.7 18.3 An earth fill when compacted, will occupy a net volume of 187,000 cy. The borrow material that will be used to construct this fill is a stiff clay. In its bank condition, the borrow material has a wet unit weight of 129 pcf and a water content of 16.5%. The fill will be compacted to a dry unit weight of 114 pcf at a moisture content of 18.3%. Compute the required volume of borrow pit excavation.
