Purpose Of Compaction Types Of Compaction

A well-graded soil can be compacted to higher density. LAYER THICKNESS. The more the thickness of layer of earth subjected to field compaction, the less the energy input per unit weight of soil and hence, less is the compaction under each pass of the roller. Suitable thickness of soil of each layer is necessary to achieve uniform thickness.
