Abstract (en)
Apparatus for heating material such as asphalt for filling potholes in which a drum (12) is rotatable about its axis (13) and has an outlet opening (15) at one end and a port (17) at the other end. An auger (36,37) is mounted within the drum (12) so that when the drum (12) is rotated in one direction material is discharged through the outlet opening end (15) and when it is rotated in the other direction it is moved away from the outlet opening (15). A flashback condition burner (18) is mounted with its discharge opening (18A) in the port (17) to discharge fully combusted hot gas into the drum to heat material therein. The burner can be dismounted to preheat and clean out a pothole in a road surface.
