Question
A proctor compaction test was conducted on a soil sample, and the following observations were
made:
Water content, percent 7.7 11.5 14.6 17.5 19.7 21.2
Mass of wet soil, g 1739 1919 2081 2033 1986 1948
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) and the optimummoisture content (wopt %)
