For vibratory rollers, the static weight of the machine plus the force generated by its eccentric motor creates centrifugal force, which helps determine the achievable compaction depth. Too heavy of a machine used on a thinner lift can cause over-compaction, and too light of a machine on thicker lifts can cause the base of the lift to not be

Compaction is a process that brings about an increase in soil density or unit weight, accompanied by a decrease in air volume.There is usually no change in water content.The degree of compaction is measured by dry unit weight and depends on the water content and compactive effort (weight of hammer, number of impacts, weight of roller, number of passes).
