WebbStandard Proctor Test Vs. Modified Proctor Test for Soil. The Standard Proctor Test, also known as the Proctor Compaction Test, was first developed by Ralph R. Proctor in the 1930s. It is a laboratory test used to determine the maximum dry density and optimum moisture content of the soil. Ralph R. Proctor went on to teach at the University of Arkansas. In 1958, the modified Proctor compaction test was developed as an ASTM standard. A higher and more relevant compaction standard was necessary. There were larger and heavier compaction equipment, like large vibratory compactors … Visa mer 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. … Visa mer The original Proctor test, ASTM D698 / AASHTO T99, uses a 4-inch-diameter (100 mm) mould which holds 1/30 cubic feet of soil, and calls for compaction of three separate lifts of soil … Visa mer • Civil engineering • Earthworks (engineering) • Geotechnical engineering Visa mer Proctor's fascination with geotechnical engineering began when taking his undergraduate studies at University of California, Berkeley.
