Wet and dry density of soils are important values for geotechnical engineers in determining over-burden stresses, void ratios, maximum compaction and percent compaction of soils. Density value can also aid in the evaluation of soil strength and sensitivity. While reporting on soil density has been part of routine laboratory testing for years, there have been no standards that outlined procedures…
