Earthwork: Vincent Chu Answers

Is it worthwhile to carry out tests on particle density of soil particles for geotechnical design?

Particle density of soils is defined by the ratio of soil particle mass and soil particle volume.

Depending on soil types, the range of variation of soil particle density varies by about 4% i.e. not very significantly.

Therefore, it may not be worthwhile to order laboratory tests and incur additional expenditure just to determine the particles density since the variation of particles density is not significant.
