A modified Proctor Test resulted in an optimum moisture content of 8 percent with a dry density of 128 lb/cu ft. Field testing using a sand cone resulted in the following: Volume = 166 cu in. with a wet weight of 11.6 lb and a dry weight of 11.2 lb. What are the field dry weight, field density, and percent of optimum density? If the specifications require a minimum of 95 percent, is compaction adequate? What changes can be made to enhance compaction?
