A sample of sand above the water table was found to have a natural moisture content of 10% and a unit weight of 120 Ib/ff3. Laboratory tests on a dried sample indicated values of void ratio as 0.45 and 0.90, for the densest and loosest states respectively. Compute the (a) degree of saturation, and (b) relative density. Use Gs=2.65.

Soil Compaction Test

Soil compaction is the major area of geotechnical engineering. Soil is composed of multiple pores present on its surface, while the soil is mainly composed of gravel, sand, rocks, etc. The arrangement of these rocks and gravels is such that they build up voids (spaces) between them, which allows spaces for the roots of the plants and crops to spread and absorb the required amount of nutrients. Soil compaction is a major problem primarily caused by human activities, micro-organisms, and other multiple factors.
