The Operational Benefits of Combi Rollers

Asphalt compaction practices vary from contractor-to-contractor and region-to-region — larger asphalt paving projects generally rely on some combination of double-drum vibratory and pneumatic tire rollers to complete the work. The double-drum vibratory compactor provides the brute force of compaction while the pneumatic tire roller provides varied weight through ballasting, and a kneading action that results in excellent density, fewer voids and a well-sealed finish.

The continued adoption of combi rollers — a vibratory steel drum on the front and a sequence of pneumatic tires on the back — has provided another option for paving contractors that ultimately delivers the best attributes of each standalone design.
