Q1: The results of a standard Proctor test are given in the table. The volume of the proctor mold used was 1000 cm'. The specific gravity (Gs) of the soil is 2.65 Mass of moist soil in the mold (Kg) Moisture content (%) 1.75 13 1.86 15 1.92 17 1.83 19 1.72 21 a. Plot the graph of dry density (Kg/m³) against moisture content (%), the zero air void line (ZAVD) and determine the maximum dry density and optimum moisture content. b. A sand cone replacement method test in the field was performed to calculate the relative compaction. The result shows that, the moisture content (w) and the relative compaction (Rc) in the field were 12% and 85% respectively. Calculate the bulk density in the field according to the given data.
