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 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 tranversely 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. The high capacity loading conveyor can be equipped with an extendable trough which has a pivotally attached trough floor with front and side plates. The extendable trough provides a large area which facilitates discharge of paving material from frameless trailers and allows for the early departure of the supply trucks from the conveyor. The final discharged paving material…
