 Tandem Vibratory Rollers

Tandem vibratory rollers compact freshly placed asphalt mats to specific densities using two, smooth steel drums that vibrate to consolidate the material. Many have sophisticated systems that continually measure density as compaction progresses and adjust compaction effort to avoid over-compaction. Using GPS and proprietary software, some rollers can capture a digital record of compaction results.

Rear oscillation paired with front vibration is featured in the HD12VO and HD14VO double-drum rollers.

Tier 4-Final DD25B double-drum compactor has a Volvo D1.7A 25-horsepower diesel.

Models BW141AD-5 and BW151AD-5 double-drum vibratory compactors have been upgraded to Tier 4-Final.

Five rollers from Chicago Pneumatic are now available in North America: three tandem rollers and two soil compactors.

New frame design and a Tier 4 engine mark the improvements in models BW141AD-5 and BW151AD-5 tandem vibratory rollers.
