Question 4: Soil compaction Standard compaction tests were performed on a brown-grey clayey-silt (p = 2.64 Mg/m³). Details and results for the tests are recorded in the following table. You are required to: (a) Plot dry density against water content w. (b) Establish the maximum dry density and optimum water content. (c) Compute the void ratio at the optimum point. (d) Compute the degree of saturation at the optimum point. (e) Plot the zero air voids curve on the same coordinate system. G₂ (1-A) (%d= -Yws A-air content) 1+ WG, Dry density 1.691 1.715 1.755 1.747 (Mg/m³) Water 9.3 11.8 14.3 17.6 content (%) 1.685 20.8 1.619 23.0
