Abstract:
1. An apparatus for repairing potholes in a roadway surface, comprising: a frame supported for movement over the roadway surface by ground-engaging wheels supported on at least one axle; a fill material hopper supported on said frame to hold a supply of asphalt fill material, said hopper terminating in a delivery chute to direct the flow of fill material into a pothole; a road heater forwardly mounted on said frame to be positionable adjacent to said roadway surface to heat and soften said roadway surface; a tack coat spray apparatus for spraying a coating of a tack coat onto a bottom surface of said pothole; a plurality of screening doors arranged transversely on said frame, each said screening door being vertically movable to vary the position of said screening door relative to said roadway surface, said screening doors being operable to screen off fill material in said pothole to an elevation above said roadway surface corresponding to the position of each respective said screening door; a compacting roller supported from said frame rearwardly of said screening doors to compact said fill material to the level of said roadway surface; and a height adjustment mechanism mounted on said frame to sense a depth dimension of said pothole along a transverse width dimension of said pothole, said height adjustment mechanism being operatively coupled to said screening doors to affect a positioning of said screening doors to a position reflecting said depth dimension.
