ABSTRACT:
This invention relates to a method and apparatus for repairing asphalt concrete road surfaces wherein a tractor a steam box and a car mounted with a screw cutter are coupled in this order and a series of linearly operated equipment is used on the asphalt concrete paved road surface, including a heater car, an asphalt finisher and a road roller in this order after the car. Each of the equipment is made to advance at low speed and the asphalt concrete paved road surface is artificially heated by the steam box to impart fluidity to the road surface, after which it is cut with the screw cutter and the cut asphalt concrete is conveyed into a heating chamber of the heater car, and water content in the asphalt concrete is removed by heating and stirring. The resulting asphalt concrete is adjusted to an optimum temperature suitable for asphalt concrete paving, and then is discharged from the heating chamber, and charged onto the surface of the cut road directly and thereafter the asphalt concrete paved road surface is teated by using the asphalt finisher and the road roller.
