Roadtec SB-2500e Material Transfer Vehicle

The SB-2500e shuttle buggy MTV has a patented anti-segregation triple-pitch auger that remixes materials just before they are delivered to the asphalt paver at rates of up to 600 tons per hour. The triple-pitch auger located in the bottom of the hopper remixes the contents of the storage hopper. The mixing action equalizes temperatures and evenly mixes large and small particles, the company says. It has a 25-ton surge capacity.

The front hopper has a steep slope and vibrating bottom plate that prevents material build-up. Operators can adjust the hopper position from either of two separate control boxes. They can also adjust the position of the push roller for different truck designs. A 300-horsepower Cummins QSL 9 engine meets Tier 4 standards.
