Soil Compaction : Mechanics Factors Affecting

2021-3-17  Soil Compaction is a method of stabilizing loose soil by densification, which can be achieved with either static or dynamic load. At constant water content, the process requires a permanent reduction in the amount of air voids.. The most popular and least costly form of soil improvement method is compaction of soil. It improves the soil’s shear strength and thus its stability and bearing ...
