compaction rate of gravel

Soil compaction Wikipedia

In geotechnical engineering, soil compaction is the process in which a stress applied to a soil causes densifiion as air is displaced from the pores between the soil grains. When stress is applied that causes densifiion due to water (or other liquid) being displaced from between the soil grains, then consolidation, not compaction, has occurred.

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.
