3.3 The following test results were obtained on a clayey soil that has been proposed for a landfill liner: • Modified Proctor Test: (70)max = 122 Ib/ft° (19.2 kN/m), wegt = 12.0%, • Standard Proctor Test: (7)max = 117 lb/ft (18.4 kN/m), wogt = 14.0%, • Reduced Proctor Test: (70)max = 113 Ib/ft (17.7 kN/m), wogt = 16%, Index Properties: G, = 2.78, %. = 62.4 lb/ft° (9.81 kN/m). Estimate the degree of saturation of the soil at the point of optimum water content and maximum dry unit weight based on these three compaction tests. What influence does increasing compactive effort have on the saturation at optimum water content?
