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.

Compaction of Soil - Test Methods and Effect on Properties ...
Compaction of soil is the pressing of soil particles close to each other by mechanical methods. Air during compaction of soil is expelled from the void space in the soil mass and therefore the mass density is increased. Compaction of soil is done to improve the engineering properties of the soil. Compaction of soil is required for the ...
