Compaction and Consolidation Overview

proctor test device

Definition of Compaction

Compaction is the process by which the soil particles are rearranged artificially and packed together into a closer state of contact by mechanical means in order to improve bearing capacity by decreasing porosity and increasing dry density. Compaction is the comparatively rapid process of reduction mainly air void of soil under short time dynamic load condition.

Common Types of Compaction

Common methods of compaction in the field are rolling, Ramming, and Vibration etc.
R.R. Proctor developed laboratory test procedure which may serve as a guide and a basis of comparison for field compaction.

Consolidation and Compaction

Consolidation and compaction are quite different in many manners although the basis is same i.e. reducing the voids and getting greater density than before. Consolidation is a natural process where as compaction is a artificial process. Consolidation occurs due to static load where as compaction occurs due to dynamic load.
Field compaction can be examined by using proctor test or modified proctor test.
