The results of a standard Proctor test are given in the following table.
a. Determine the maximum dry density (kg/m3) of compaction and the optimum moisture content. Given mold volume = 943.3 cm3.
b. If specification calls for 97% relative compaction in the field, what would be the field dry density and the range of acceptable moisture content?
