a. Determine the maximum dry density (kg/m3) of compaction and the optimum moisture content. Given: volume of
mold: 943.3 cm3.
b. What is the degree of saturation at optimum moisture content? Gs=2.75
c. If the required field dry unit weight is 1470 kg/m3, what is the relative compaction?
d. What should be the range of compaction moisture contents in the field to achieve the above relative compaction?
