Proctor compaction test - Wikipedia
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 R. 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 compaction.

Shrinkage factors for sand - Earthwork/grading engineering ...
Jul 02, 2010· Determine the in-situ relative compaction. Contrast that value to what you've specified. Determine the "shrinkage factor." You will likely find that the in-situ density is close to what you want to specify. Let's say it's 93 percent and you want 95 to 100. So, that's an increase of about 5 percent.
