Abstract
A road patching vehicle for patching damaged areas or potholes of various sizes and shapes on a roadway includes a boom assembly pivotally mounted at or on the forward end of the vehicle with a nozzle mounted at or toward the forward end of the boom. Various hoses connect the nozzle to a source of pressurized air, a source of patching emulsion (such as an asphalt emulsion), and a source of a rock aggregate with the vehicle operator controlling the flows individually or in various combinations thereof to prepare and then fill the pothole or other road defect to effect a patch. The nozzle is mounted on a pivot or journal to allow controlled pivoting or tilting of the nozzle under control of the operator in at least one degree of freedom. In a variant of the preferred form, the nozzle is mounted for control pivoting or tilting under the control of the operator in at least two degrees of freedom.
