Abstract:
An improved road maintenance truck includes a pair of hydraulically powered roller assemblies mounted to the underside of the vehicle frame and a vertically movable compression plate mounted to the vehicle frame. Each roller assembly has a compressive roller which runs the width of the truck. Two hydraulic actuators on each end of the vehicle raise and lower the roller into place. These independent rollers allow a road patching crew to selectively lower the roller for repairing road while initially flattening the patching material with the front roller and compacting the patching material with the rear. The compression plate is mounted to an actuator which selectively raises and lowers the compression plate to compress road patching materials. A roller heating system draws engine coolant through the rollers to heat the rollers and to reduce the heat built-up in the engine.
