Proctor compaction test

Jan 05 2007The 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 [] 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

What is Crusher Run?

What is Crusher Run and Why is It Used? (Also Called Crush and Run) Crusher run is a blended mix of coarse aggregate and fine aggregate The combination of both crushed stone and stone dust creates a low void content (the amount of space or air between the pieces of rock in a mix) that is valuable in concrete construction for its compaction ability and drainage characteristics
