Volvo Construction Equipment has expanded its small compaction line with the CR30B and CR35B combination rollers, which were introduced at World of Asphalt 2018.

Built on the proven platform of preceding models, these versatile, next-generation machines can be used in a variety of applications including driveways, small paths, patchworks or road shoulders, according to  Product Manager Mark Eckert.

The CR30B and CR35B deliver a dense, high-quality mat surface thanks to the combination of two compaction methods, he says, pointing to the front drum and rear tires of the CR30B on display at World of Asphalt.

The machines use the high-frequency vibration of the front drum to achieve density targets. The four pneumatic rear tires manipulate the compacted material, ensuring impermeability and smoothness.

The Kubota 49.6 horsepower engine in these models meets Tier 4 Final emissions regulations. A passive regeneration system cleans the filters automatically, eliminating the need for the machine to stop or for operator input.

Fuel use is further trimmed, thanks to the optional auto-idle feature, which reduces engine speed when controls are inactive for more than 60 seconds.


Controlled and consistent compaction


Eckert notes that the CR30B and CR35B combination rollers offer consistent compaction – in part because the auto-vibration feature automatically engages vibration when the machine reaches 1.5 miles per hour and disengages when the speed drops below 1.2 miles per hour for reduced risk of over-compaction.

Optimizing finished pavement quality, the drum edges are chamfered and rounded to avoid marking the mat while rolling. The pressurized water spraying system and a separate emulsion tank prevent material pick-up. The operator can easily adjust the water flow rate and emulsion flow rate independently, for greater productivity and ease of use, Volvo says.

The new side console and display enables operators to make adjustments on the fly. The operator seat can also slide laterally according to individual preferences and jobsite requirements. For increased rolling precision, the engine hood is sloped, offering a clear forward view of the job site, as well as unobstructed sightlines down to the drum and spray bars.


Reducing downtime through durable components, easy maintenance

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.

Volvo also offers a range of solutions to optimize machine uptime and reduce operating costs. The CR30B and CR35B are Tech Tool and compatible with MATRIS (Machine Tracking Information System), which can help speed diagnostic time. CareTrack, the Volvo telematics system, is also available as a factory option for proactive machine monitoring.
