The new Terex Cedarapids CR662RM RoadMix material transfer vehicle (MTV) from Terex Roadbuilding meets all state requirements for continuous, non-contact interstate paving.

Weighing 50,800 lbs. (23,042 kg) and featuring a rubber-track drive system that evenly distributes the weight over a larger area, RoadMix has a relatively low ground contact pressure, enabling this MTV to be used on base as well as top courses.

The CR622RM is the first and only MTV to reblend 100 percent of the asphalt, reducing the chance for material and thermal segregation, according to the manufacturer.

The CR622RM MTV is built around the remix anti-segregation system. Material dumped into the RoadMix’s 16.7-ton (15-t) receiving hopper is immediately reblended by two sets of two counter-rotating augers.

The constant 12-in (30.5 cm) diameter, variable pitch augers uniformly pull material from all areas of the hopper. RoadMix delivers a remixing of material, which is beneficial in reducing segregation when working with coarse aggregate base mix designs.

The augers channel the material to the rear of the machine, offering a reduced handling time. A short delivery conveyor carries the asphalt to a long conveyor that swivels 55 degrees left or right of center, enabling offset paving. The swiveling conveyor has a hydraulically variable discharge height from 73 to 116 in. (185 to 294 cm).

When the CR662RM is not needed as an MTV, the rear conveyor assembly can be removed and replaced with a Terex Cedarapids screed, allowing it to be used as a paver.

The RoadMix spreading augers are powered by an outboard drive that does away with the center auger chain drive, eliminating the need for reverse augers. When equipped as a paver, RoadMix features the same in-hopper auger reblending technology as Terex Cedarapids Remix pavers, allowing the paver to combat both material and thermal segregation.

The CR662RM RoadMix machine’s rubber-track drive system features the Terex Cedarapids Smartrac self-tensioning track system.

This feature automatically maintains proper tension on the track at all times, eliminating the need for manual track adjustments, extending track component life and reducing the chance for track disengaging. RoadMix’s fume recovery system mitigates captured asphalt fumes from the conveyor/screed area.
