Caterpillar CB-335E

By Walt Moore, Senior Editor | September 28, 2010

Caterpillar's CB-335E is a combination roller, weighing in at 8,092 pounds, that uses a drum 31 inches in diameter and 51 inches wide. Vibration frequency is 4,140 vpm, and the CB-335E generates 7,267 pounds of centrifugal force. This 50-hp machine's four rear tires assist in the compaction process by bringing aggregate fines in the mix to the top of the mat to create a tight, smooth surface that resists water intrusion.
