ABSTRACT:
The invention relates to a method for repairing ruptured longitudinal seams or cracks in road surfaces which consist of a thermoplastic material and particularly of an asphalt coating including bitumen and mineral constituents, by which, under the application of heat, new coating material is applied and consolidated in the area of the longitudinal seams or cracks, wherein at first mud and humidity is removed from, and out of, said longitudinal seam or crack, said longitudinal seam is subsequently softened by heating, said softened coating is loosened from the underground and is compounded with the new material and/or liquid or liquified aggregates and is finally incorporated and consolidated again.
The invention relates also to an apparatus for performing the method, comprising a chassis including its own drive engine and at least one heating device and means for loosening the road coating arranged behind it as seen in the direction of motion, wherein as the means for loosening said road coating a small roller provided with chisels and rotating in a direction opposite to the direction of motion is provided, which roller is arranged in the discharge area of a container holding said new coating material such that when rotating said roller in the discharge area of said container, compounding the old coating material transported up by said chisels and of the new coating material is accomplished.
