Combination Rollers
Volvo Construction Equipment launched the CR30B and CR35B combination rollers at World of Asphalt 2018, adding to its small asphalt compaction line. These machines are powered by a fuel-efficient, low-emission engine and are 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. 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 tyres manipulate the compacted material, ensuring impermeability and smoothness of the mat.

Both models are powered by a Kubota 49.6 hp 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. The CR30B and CR35B combination rollers offer consistent compaction due to a handful of advanced features. The auto-vibration feature automatically engages vibration when the machine reaches 1.5 mph and disengages when the speed drops below 1.2 mph, for reduced risk of over-compaction.

The new combination rollers promote uptime through durable components and simple maintenance requirements. The 79-gallon water spraying system increases time between refills. The low positioning of the water and emulsion tanks enable them to be quickly and easily filled from ground level. And the hinged hood provides clear access to the engine, hydraulics, fuses and relays for swift and convenient servicing.
