Transcribed Image Text: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 replacement
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 = 2220g
Weigh of oven dry soil
Max dry density in the laboratory
Reduction Factor
= 1729g
= 19.85 KN/m
= 12%
7. Find the in situ unit weight of soil?
a. 1.71 g/cc
8.Find the in situ water content of soil?
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?
a, 85.10%
b. 23.42%
c. 28.40%
d. 25.54%
b.89.26%
c. 86.32%
d. 87.14%
