The RT-500 is intended for use in cold-in-place recycling projects using the recycling train concept, consisting of tanker trucks, cold planers, crushing and screening units, mixers, pavers and rollers. The new RT-500 can handle up to 600 tons per hour of material and is designed to crush and screen the RAP produced by the RX-900 cold planer. The on-board pugmill mixes emulsion into the recycled material.

The RT-500’s double-deck screen receives the milled-up material from the RX-900 conveyor. Any oversized material goes through the RT-500’s Telsmith 3048 impact crusher and back to the screen via a two-conveyor return circuit.

Material that passes the screen drops onto a 48-in. weigh belt. The belt’s electronic scale communicates with the blending computer, which in turn adjusts the flow of additives that go into the RT-500’s JCI/KPI Model 52 pugmill mixer. This twin shaft mixer has a capacity of 600 tons per hour. After mixing, the material is discharged in a windrow onto the roadway. The whole RT-500 system is run by electric motors powered by a Caterpillar C-9 generator set.
