Sand replacement density

Sand replacement density (SRD) tests are used to measure the in-situ density of natural or compacted soils using sand pouring cylinders The in-situ density is typically used for highway or pavement design purposes to estimate the relative density of base course or subgrade materials.

Sand replacement

Dec 12, 2013· The relationship that can be established between the dry density with known moisture content is as follows: Sand replacement method (standard method, but does not apply to fill a big stone embankment and other porous materials, holes or large degree of compaction test) is the use of the basic principles of particle size 030 ~ 060mm or 025.

Proctor compaction test

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 densityThe 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.
