Determine the relationship between moisture content and density of soil. In compaction of soils, the main aim is to keep the soil particles close together which leads to improve dry density of soil. The soil with maximum dry density is suitable for the several constructional purposes. But maximum dry density of soil through compaction will be possible at a particular moisture content called optimum moisture content.
