Dec 06, 2017· The specimens of the soil mixtures were prepared using two compaction energy levels – namely, the British standard light (BSL) and West African standard (WAS) – at moulding water contents of −2, 0, +2, +4% of the optimum moisture content. The results showed that consistency limits and optimum moisture content reduced, while the maximum ...

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 [], 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 ...

Renewable energy targets have become a defining feature of the global energy landscape. As of mid-2015, 164 countries around the world have adopted at least one type of renewable energy target, up almost four-fold from 43 countries in 2005. Two more countries have set renewable energy targets at the sub-national level only (Canada

test using increased energy of compaction was then necessary to reproduce these higher compacted densities, so a test was introduced which used a heavier rammer with the same mould. This intensified procedure became known as the modified Proctor test. It is similar to the British Standard heavy compaction test.
