Compaction
ByBernardo Caicedo
Pages 71

Soil compaction is the process of increasing soil density by removing air from within voids. Proctor’s methodology is at the base of the classical approach to soil compaction. Proctor [337] conceived his approach as a way to reproduce field compaction in a laboratory by relating dry density ρ d to water content w while applying controlled mechanical energy to soil.
