Answer 6.4 

= 2.75, calculate the zero-air-void unit weight for a soil in lb/ft³ Given G, w = 5%, 8%, 10%, 12%, and 15%. 6.1 6.4 The results of a standard Proctor test are given below. Determine the maximum dry unit weight of compaction and the optimum moisture content. Weight of wet soil in the mold (Ib) GsYw Vzav = 1+ wG5 Volume of Moisture Proctor mold (ft³) content (%) GSYW 1/30 3.26 8.4 Ya = 1/30 1+ GW 4.15 10.2 1/30 4.67 12.3 1/30 4.02 14.6 Se = Gsw 1/30 3.63 16.8 6.5 For the soil described in Problem 6.4, if G, = 2.72, determine the void ratio and the degree of saturation at optimum moisture content.
