A mobile pothole patching machine comprises a vehicle frame which carries a hopper for receiving a filler material for the pothole. Underneath the vehicle is mounted a belt conveyor which can be moved back and forth longitudinally of the vehicle and can be pivoted side to side about a vertical axis. At a front of the conveyor is mounted a laying apparatus including a roller and a rake. The rake can be raised relative to the roller and both can be raised relative to the ground by a lifting apparatus attached to the conveyor. A fabric wiper carries an anti-sticking agent draped over the top of the roller. A blow heater is mounted on the laying apparatus and has a pipe directing heated air into the potholes. In front of the rake is mounted an air jet and a bonding agent jet for cleaning and bonding the pothole. The hopper includes a pair of cover plates which can be pivoted out to the sides on two links. The material from the hopper is conveyed by an auger flight with a canopy over the auger flight which can be moved longitudinally to support the weight of the filler material when the hopper is filled and to release the filler material to the auger flight.
