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.
The best available technique of measuring critical residual moisture is the determination of the relative permittivity by HF (High-Frequency) methods. While each mixture of building materials aspires to a different equilibrium moisture content, it is necessary to determine its specific moisture profile.
