e) If G, 2.70, what is the degree of saturation of the field sample? Gs = f) If the field sample was saturated at constant total volume (i.e., the air in the voids was replaced by water), what would be the resulting moisture content? g) It is desired to plot the zero-air-void curve. For this purpose, compute the zero-air-void unit weight associated with moisture contents of 20.0, 22.0 and 24.0%. Figure 1 shows the laboratory field compaction curve for a given soil. Specifications call for the compacted unit weight to be at least 95% of the Standard Proctor Maximum and within of the optimum moisture content. When a sample of the soil was excavated from the field, it had a volume of 57.6 in³. The sample weighed 4.00 pounds wet and 3.36 pounds dry. 108.0 Dry unit weight (pounds per cubic foot) 106.0 104.0 102.0 100.0 12.0 14.0 16.0 18.0 20.0 22.0 24.0 26.0 Moisture content (%) Figure 1: Results of laboratory standard Proctor compaction test. Determine the following: a) The field moisture content. b) The compacted dry unit weight. c) The relative compaction. d) Does the soil meet specifications?
