Results of a standard compaction test (mold volume 943.9 cm3 ) are: Trial No. 1 Mass of soil + mold 5619 g Mass of mold 3735 g Water content test Mass of sample + container 288.26 g Mass of dry sample + container 265.39 g Mass of container 104.31 g Trial No. 2 Dry density 1795 kg/m3 w=14.9% Trial No. 3 Dry density 1828 kg/m3 w=15.6% Trial No. 4 Dry density 1832 kg/m3 w=16.5% Trial No. 5 Dry density 1796 kg/m3 w=17.6% Complete the calculations for trial No. 1. Draw the moisture-density curve using Excel or other spreadsheet programs. Include ZAV curves at w=16%, 17%, and 18%. (The relative density of the soil is 2.65.) Find the maximum dry density and the optimum water content.
