Road Base Rock Hammer Earthmoving

Improper compaction can lead to a multitude of issues and ultimately pavement failure in a shorter time than allowed for in the design. One of the main issues arising from under compaction of road base layers will be rutting of the surface. This is due to the movement of particle during cycles of wetting and drying during the life of the pavement.
