Abstract
Apparatus for patching or filling paved road surface cracks or joints includes means for simultaneously dispensing molten asphalt bitumen and monofilament strands of reinforcing fiber, wherein fiber roving is chopped into discrete segments and intermixed with the molten asphalt as the patching or joint filling application occurs. The apparatus is intended to be mounted on a mobile rig to facilitate its use, and includes an arrangement wherein the molten asphalt is continuously pumped out to a dispensing nozzle assembly and back to the storage reservoir on the rig whereby the flow maintains a continuous circuit from which the molten asphalt is selectively withdrawn for use in patching and filling operations. Also included is a means for selectively purging the circuit after use of the apparatus, and the method of utilizing the apparatus.
