The results of a standard Proctor test are given in the
following table.
a) Determine the maximum dry unit weight of compaction and the
optimum moisture content. Given: Mold volume = 1/30 ft3.
b) Determine the void ratio and the degree of saturation at the
optimum moisture content. Given: Gs = 2.69.
