Situation 3: The maximum dry density of a soil was found to be 1.49mg/m' at optimum moisture content of 12.7% the required compaction is 95%. To determine the parameters of the said soil, sand replacemer method was conducted and the data are as follows: Volume of soil excavated from the hole = 0.0013m' Weight of soil from the hole when wet Weigh of oven dry soil Max dry density in the laboratory Reduction Factor 7. Find the in situ unit weight of soil? a. 1.71 g/cc 8.Find the in situ water content of soil? = 2220g = 1729g = 19.85 KN/m = 12% b. 1.66 g/cc c. 1.98 g/cc d. 2.66 g/cc a. 27.46% 9.Does it meet the required degree of compaction? If yes/no by what percent? b. 23.42% c. 28.40% d. 25.54% 85 10% h 89 26% C 86 32% d 87 149%
