Compaction of Soil

Compaction is the application of mechanical energy to a soil to rearrange the particles and reduce the void ratio The principal reason for compacting soil is to reduce subsequent settlement under working loads As water is added to a soil at low moisture content it becomes easier for the particles to move past one another during the application of the compacting
