BOMAG’s CR662RM RoadMix
BY AsphaltPro Staff
When the paving crew needs to switch from a paving job that specs a material transfer vehicle (MTV) to a job that requires traditional laydown, the rubber track Cedarapids CR662RM RoadMix from BOMAG, Ridgeway, South Carolina, offers a one-machine transition. Here’s how it works.
First, a new 260-horsepower Tier 4 Final Cummins diesel engine drives the RoadMix.
As the RoadMix takes on mix from the haul truck, improved Remix Anti-Segregation System delivery augers, which now feature hard-faced back sides, move the material to the back. The two sets of two variable-pitch, counter-rotating augers uniformly draw down material from inside the hopper to remix 100 percent of the asphalt. Auger pitch spacing transitions from 10 inches at the front of the hopper to 12 inches at the rear to channel material to the 30-inch wide transfer conveyor at a throughput capacity in excess of 600 TPH.
The transfer conveyor feeds material at a discharge height of 73.2 to 115.8 inches to a paver’s receiving hopper for non-contact paving, and swivels 55 degrees left or right of center for off-set paving.
When the crew needs to use the CR662RM for mainline paving, the team can remove the rear conveyor assembly from the tractor and replace it with the Stretch 20 or Fastach 10 screed assembly in less than four hours, according to the manufacturer. “If necessary, a contractor could pave with the RoadMix in the morning and use it as an MTV in the afternoon,” Henry Polk, product marketing manager, said.
When equipped as a paver, the counter-rotating augers draw material from the front of the hopper to the back, remixing 100 percent of the asphalt, channeling material to the spread augers. Two independently controlled, variable-speed outboard drive motors that power the spread augers eliminate the need for a center gearbox drive to reduce the occurrence of centerline segregation.
