One of the field tests last summer on a Benton County, Iowa, highway just happened to coincide with a record-breaking heat wave. The RoadMix MTV kept its cool, allowing the L.L. Pelling Co. of North Liberty, Iowa, to establish a continuous paving process so the contractor could lay a superior mat and use fewer trucks.
The 12-in. constant-diam., variable-pitch augers reblend 100% of the material to combat material and thermal segregation. Remixing benefits both the MTV and paver functions of the machine. Machine utilization is a key consideration for today’s paving contractor, especially when it comes to the hundreds of thousands of dollars spent on material transfer vehicles. For machines that typically average utilization rates of less than 50%, contractors have had to think long and hard before purchasing an MTV.
Terex/Cedarapids now makes this decision much easier with its quick-attach spreading auger and screed designs for the RoadMix, which allows the MTV also to be used as a paver. This double duty will boost utilization rates for the CR662RM by giving contractors two machines in one.
The change from MTV to paver is accomplished in a matter of hours. Contractors simply drop the conveyor legs, disconnect the assembly from the tractor and drive away. After attaching the hydraulic cylinders, tow arms and spreading auger assembly to the tractor, the operator simply backs into the screed. A new outboard drive spreading auger design, currently in field testing, promises to reduce the occurrences of centerline segregation.
