4) If the required field dry unit weight is 18.5 kn/m3, what is the relative compaction? 5) What should be the range of compaction moisture contents in the field to achieve the above relative compaction? 6) If the minimum and maximum void ratios are 0.31 and 0.82, respectively, what is the relative density of compaction in the field?
Results of a standard proctor ompaction test on a silty sand are shown.
PLEASE COMPLETE SOLUTION.
1) Find the maximum dry unit weight and optimum moisture content.
ANS: ydmax = 19 kn/m3 omc = 10% or 0.1
2) What is the moist unit weight at optimum moisture content?
ANS: 20.9 kn/m3
3) What is the degree of saturation at optimum moisture content? Given: Gs = 2.69
ANS: 69.17%
