Soil compaction - Wikipedia

In geotechnical engineering, soil compaction is the process in which stress is applied to a soil causes densification as air is displaced from the pores between the soil grains. When stress is applied that causes densification due to water (or other liquid) being displaced from between the soil grains, then consolidation, not compaction, has occurred. Normally, compaction is the result of heavy machinery compressing the soil, but it can also occur due to the passage of, for example, animal feet.

Soil compaction is a critical part of most engineered structures that use the earth or soil as a foundation or a base for support. The soil’s engineering properties, including strength, compressibility, and permeability, can be improved and become more predictable with the proper degree of compaction.

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 Roscoe Proctor [de], 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. His original test is most commonly referred to as the standard Proctor compaction test; his test was later up…

Soil in place is tested for in-place dry bulk density, and the result is divided by the maximum dry density to obtain a relative compaction for the soil in place. In the other hand, soil compaction test is carried out in the laboratory in determining the ideal volume of water to be poured while compaction the soil on site so that the required compaction degree can be obtained.
