With the latest engine technology and features that help to provide a dense, high-quality mat, the CR30B and CR35B are the ideal fit for small-scale compaction projects.
Volvo Construction Equipment launched the CR30B and CR35B combination rollers at World of Asphalt, adding to its small asphalt compaction line. These versatile machines are powered by a fuel-efficient, low-emission engine and packed with features that deliver a smooth and dense mat surface.
Built on the proven platform of preceding models, these next-generation machines can be used in a variety of applications, such as driveways, small paths, patchworks, or shoulders on roads. Whatever the job, the CR30B and CR35B deliver a dense, high-quality mat surface thanks to the combination of two compaction methods. The machines use the high-frequency vibration of the front drum to achieve density targets, and the four pneumatic rear tires manipulate the compacted material, ensuring impermeability and smoothness of the mat.
Both models are powered by a Kubota 49.6 horsepower low-emission, fuel-efficient engine. They meet Tier 4 Final emissions regulations and feature a passive regeneration system that cleans the filters automatically, thereby eliminating the need for the machine to stop or for operator input. Fuel use is further reduced thanks to the optional auto-idle feature, which reduces engine speed when controls are inactive for more than 60 seconds.
