2) The results of a standard compaction test are shown in the table below. (20 pts) Water content (%) Bulk unit weight (kN/m³) (a) (b) (c) 6.2 16.9 8.1 18.7 9.8 19.5 11.5 20.5 12.3 13.2 20.4 20.1 Plot Yd vs. w. and then determine the maximum dry unit weight and optimum water content. What is the dry unit weight and water content at 95% standard compaction, dry of optimum? Determine the degree of saturation at the maximum dry density. (d) Plot the zero air voids line.
