The new models of the Caterpillar B-Series Tandem Vibratory Rollers are the CB44B and CB54B, and the CD44B and CD54B.
The optional Cat Compaction Control system combines infrared temperature sensors with mapping to keep the operator informed of current mat temperatures, machine position, and coverage completion. This system enhances nighttime performance and also records information for future process analysis and quality control documentation.
When combined with drum edge and drum surface lighting, Cat Compaction Control optimizes jobsite awareness in low-light conditions.
The rollers perform well in vibratory or static mode, enabling a single machine to perform breakdown, intermediate, and finishing work. The B-Series machines can be equipped with solid- or split-drum designs.
The split-drum design delivers excellent mat quality in urban environments and confined working areas where frequent turning is required. The split-drum rollers prevent tearing because the outside drum half rotates faster than the inside half, enabling turning and eliminating “pushing” of fresh asphalt.
The solid drum offers expanded vibratory choices to match amplitude and frequency requirements. This drum design performs well in high-production street and highway applications.
The CB44B and CD44B tandem vibratory rollers compete in the 7.7- to 11 U.S. ton size class, while the CB54B and CD54B compete in the 8.8 to 12.5 U.S. ton class. The Cat engines powering both machine classes meet U.S. Environmental Protection Agency Tier 4 Interim and European Union Stage IIIB engine emissions standards.
Typical applications include highways, city streets, county roads, lane additions, industrial sites, overlays, airport runways, and other production-sized paving jobs.
