Abstract
A pothole patching machine includes a container for storage of patch material, and a auger screw conveyor for conveying the patch material from the container to a ram. The ram is adapted to forcibly urge the patch material into a pothole. The ram is moveable between a retracted position and an extended position which completes one fill stroke. The ram also includes a foot plate dimensioned for positioning over the pothole and sensors for sensing when the pothole has been filled.
