Measurement of Geotechnical Properties for Engineering and Technology Students

Compaction, an artificial densification of soils, is a simple ground improvement technique, where the soil is densified through external compactive effort. It involves the application of mechanical energy to a soil to rearrange the particles and reduce the void ratio. It is a process of increasing the density of soil in a fill by reducing its void space by the expulsion of air. Compaction is usually achieved by subjecting the soil to a changing state of stress such as few repetitive cycles of ramming, rolling or vibrations. This results in a decrease in the volume of the air voids and an increase in the density of the soil.
