Fundamentals of Soil Compaction

SOIL COMPACTION Compaction is the application of mechanical energy to a soil to rearrange the particles and reduce the void ratio. 3.1 Purpose of Compaction • The principal reason for compacting soil is to reduce subsequent settlement under working loads. • Compaction increases the shear strength of the soil.
