ABSTRACT:
A paving machine employs in combination a gravity feed HMA hopper and a tack spray assembly and storage tank. Use of the gravity feed hopper permits all HMA or other paving material stored therein to be discharged directly on top of the paving machine's distributing auger. Moreover, because the gravity feed hopper takes up a relatively small percentage of the horizontal area of the paving machine, a chassis of standard or near standard dimensions can receive a tack storage tank of sufficient capacity to permit the paving machine to operate an entire day without stopping the machine to refill the storage tank. Therefore, if used in conjunction with an HMA shuttling apparatus, the paving machine can simultaneously coat a surface to be paved with a tack material and pave that surface with HMA for prolonged periods of time without stopping to refill either the HMA hopper of the tack storage tank.
