CB-634D Asphalt Compactor

Updated Oct 6, 2010

The CB-634D can be used in all phases of compaction, reducing the need for a variety of rollers. The CB-634D is capable of working as a breakdown and intermediate roller because of its high compactive forces. When operated in the static mode, the CB-634D is a perfect fit as a finish roller because of its high static pounds per linear inch (PLI). Its machined steel drums provide a smooth finish in this application.
