A field - compact sample of sandy loam was found to have a wet density of 110.4 lb/ft3 at a water content of 14%. The maximum dry density of the soil obtained in a Standard Proctor Test (SPT) was 99.6 lb/ft3. Assuming specific gravity of soil sample to be 2. 6, determine the percent compaction of the field.

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.
