A proctor compaction test was conducted on a soil sample, and the following observations were made: (fill in blanks on the charts and show all calculations below charts in calculation space provided). If the volume of the mold used was 950 cm3 and the specific gravity of soils grains Gs = 2.65, make necessary calculations and: 1. determine the wet density in g/cm3 2. determine the dry density in g/cm3 3. determine the dry unit weight in kN/m3 4. construct the compaction curve 5. determine the optimum moisture content in percent 6. determine the maximum dry density in kN/m3 7. construct the 80% and 100% saturation lines using w% = 8, 12, 16, 20, and 24 8. calculate the saturation for the maximum dry density (Υdmax in kN/m3 the optimum moisture content (wopt %)
