Abstract

An apparatus provided with a hopper having a capacity substantially equal to the capacity of a supply truck for receiving asphalt-aggregate material. A transversely disposed screw auger is provided for remixing the asphalt-aggregate material in the hopper prior to its discharge. In one form of the invention, the apparatus forms part of a self-propelled storage vehicle which transfers the material from the supply truck to a conventional finishing machine.

Claims

1. An apparatus for receiving an asphalt-aggregate material comprising:

(a) chassis means including ground engaging mobile support means and steering means for at least a part of the support means;

(b) motive power means carried by said chassis means and connected to at least a part of said support means;

(c) hopper means mounted on said chassis means in substantial symmetrical relationship with the longitudinal centerline of the chassis means;

(d) conveyor means mounted on said chassis means for transporting the asphalt-aggregate material longitudinally of said chassis means from said hopper toward the rear of said apparatus; and

(e) transversely disposed screw auger means mounted in the lower portion of said hopper means for delivering the asphalt-aggregate material from the lateral extremities thereof to the central portion of said hopper means wherein said screw auger means has a first pair of screw sets at the outer ends of the auger means and at least a second pair of screw auger sets inwardly of the first pair of screw sets, the second pair of screw sets having a pitch greater than the pitch of the first pair of screw sets for allowing the asphalt-aggregate material at the center portion of the hopper means to combine with the material transported by the first set of screw sets from the transverse extremities of the hopper means.

2. The apparatus according to claim 1 wherein said hopper has side walls of substantial height thereby providing the hopper with a capacity substantially the same as the capacity of a delivery dump-truck.

3. The apparatus according to claim 1 further including a loading conveyor for transferring material from a delivery truck to said hopper.
