Abstract
An apparatus and method for delivering asphalt-aggregate material from a plurality of supply trucks to a finishing machine. In a preferred form of the invention the hopper of the finishing machine is modified to have a capacity substantially equal to the capacity of one of the supply trucks. The apparatus is a self-propelled storage vehicle including a hopper having a capacity substantially equal to the capacity of one of the supply trucks, a high capacity loading conveyor, and a high capacity unloading conveyor system. A transversely disposed screw auger is provided for remixing the asphalt-aggregate material in the hopper prior to its discharge to the finishing machine. In the first method of operation the storage vehicle shuttles between the finishing machine and a remote location of the supply trucks and in the second method of operation the storage vehicle travels in tandem with the finishing machine as the paving operation is performed.
