Discussion: Answer the following questions by referring to relevant References. 1. Zero Air voids line should be plotted with the compaction curve plot? 2. The compaction energy per unit volume (compactive effort) used for the standard proctor test is about 600 kN.m/m³, Prove it? 3. Explain the mechanism behind the shape of the compaction curve?
A sample o f soi l compacte d accordin g t o a standar d Proctor test ha s a unit weight of 130.9 lb/ft 3 at 100 % compaction and at optimum water content o f 14% . What is the dryunit weight? If the voids become fille d with water what would be the saturated unit weight?Assume Gs = 2.67.
