Compaction

Compaction is to reduce the volumes of soil for achieving this goal the air must be removed from the soil by using force. The seeds roll in each other and in effect of using forced air mass will move from the inside of the soil. In this case, the friction between the particles increases and then the unit weight of soil will increases.The weight is a measure of soil compaction.

In order to increase density and shear force resistance is Permeability reduction. The result of permeability reduction is because the soil pores become smaller so water passes more difficult through the pores.

The different way of soil compaction due to its physical properties are non-cohesive soil compaction and cohesive soil compaction we will use the compaction of standard and modified methods in all are the same, but the difference is in the amount of weight and other specifications.
