A modified Proctor compaction test was carried out on a clayey sand in a cylindrical mold that has a volume of 1000 ml. The specific gravity of the soil grains is 2.68. The moisture content and the mass of the six compacted specimens are given here. Moisture content (%) 5.0 7.0 9.5 11.8 14.1 17.0 Mass of specimen (g) 1850 1970 2090 2110 2090 2060 a. Plot the compaction test data and determine the optimum moisture content and the maximum dry unit weight. b. Plot the void ratio and the degree of saturation against the moisture content. c. What are the void ratio and degree of saturation at the optimum moisture content?

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.
