Abstract

An apparatus for recycling asphalt pieces obtained from the repairing work site, to repair rapidly potholes and cracks in roadway and at a minimum cost, and of which it is possible to produce a usable hot asphalt at a temperature about −12 to −15 degrees Celsius.

Claims

1. An apparatus for recycling asphalt material, which comprises:

a tank housed in a casing to be protected against bad weather, wherein the casing is designed to be movable for repairing a burner located outside the tank and projects toward the interior of the tank to provide a heating flame projecting toward the interior of the tank for heating asphalt pieces obtained from the repairing work site, and wherein the outer surface of the tank is thermally insulated and covered with a box generally made of metal sheet;

a roof hinged at the upper portion of the tank for covering the top opening of the passage to prevent heat from escaping, and of which can be tilted through the manipulation of handles secured therewith; and

a door hinged at the bottom portion of the tank.

2. An apparatus according to claim 1 wherein said oil burner heats the recycled asphalt pieces disposed on a wire netting, and wherein a mass of asphalt falls gravitationally at bottom of the tank during the heating operation to be discharged from the bottom of said tank through the door for repairing potholes and cracks in roadway.

3. An apparatus according to claim 1 including plate means secured therein said tank for protecting oil burner from the hot asphalt falling at bottom of the tank.

4. An apparatus according to claim 1 including plate means secured in front of said burner for protecting said tank from the flame of the burner.

5. An apparatus according to claim 1 including deflector means for diverting heat pushed by the fan of the burner to prevent the overheating.

6. An apparatus according to claim 1 including endless screw means for agitating asphalt.
