Methods and apparatus for making an asphalt-aggregate pavement
First Claim
1. The method of laying an asphalt-aggregate pavement mat comprising the steps of:
- (a) operating a finishing machine of the type having a screed for forming an asphalt-aggregate pavement mat;
(b) operating a plurality of delivery trucks to transport the asphalt-aggregate material in a sequential manner from an asphalt plant to the job site;
(c) providing a self-propelled mobile apparatus which includes;
(i) hopper means,(ii) first conveyor means for receiving the asphalt-aggregate material from a delivery truck and for advancing the material to the hopper means, and(iii) second conveyor means for transporting the asphalt-aggregate material laterally from the hopper means to the finishing machine;
(d) operating the self-propelled mobile apparatus for transferring the asphalt-aggregate material from the delivery trucks one at a time to the hopper means; and
(e) operating the self-propelled mobile apparatus for transferring material from such apparatus to the finishing machine while the former is positioned to one side of the latter.

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.
