However, when water contents at the time of compaction are near saturation with no free water, the dry unit …
Methods used to determine maximum and minimum dry unit …
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 P… Web20 jan. 2024 · The minimum and maximum dry densities (thus, maximum and minimum void ratios, respectively) as well as Atterberg limits were determined on samples … boucher horse bit
