Compaction of soil
Compaction is the process in which densify the soil mass by means of mechanical by removing the air from the void of soil mass and particle becomes closer.
Following are the purpose of compaction
-To increase the share the strength and bearing capacity of soil.
-To reduce the compressibility
- To reduce the permeability
- To reduce the swelling and shrinkage
Factor affecting compaction of soil
-water content
-Amount of compaction
-Type of compaction
-Types of soil
-Speed of rolling
-Addition of admixture
Different types of laboratory compaction test
1) Standard Proctor test
2) Modified AASTHO Test
