Proctor compaction test

The Proctor compaction test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry density The test is named in honor of Ralph Roscoe Proctor who in 1933 showed that the dry density of a soil for a given compactive effort depends on the amount of water the soil contains during soil
