Method and apparatus for plastifying and tearing up of damaged roadsurfaces and covers

A method for resurfacing an old blacktop road surface by means of first, second, and third separate, mobile units performing a respective first, second, and third group of steps, wherein said first group performed by said first, separate mobile unit comprises the steps of:

• (a) providing, by means of a single heater, a single heat application to the old road surface for heating and plastifying the old road surface to a given depth (17),
• (b) breaking up only a top portion (18) of the heated old road surface to produce a broken-up material layer having a thickness substantially less than said given depth (17) of heated old road surface,
• (c) rearranging and distributing the broken-up material on the remaining still heated but otherwise undisturbed old road surface to produce a first profiled layer (19) of broken-up material, wherein said second separate mobile unit performs the steps of:
• (d) supplying fresh asphalt material into the third, separate mobile unit,
• and wherein said third group performed by said third, separate mobile unit comprises the steps of:
• (e) distributing fresh asphalt material on top of said profiled, broken-up layer (19) over the entire working width of the third unit while said road surface and the layer (19) of broken-up material are still sufficiently plastified from said single heat application, and
• (f) immediately profiling and compacting said fresh asphalt material as a top layer (25) together with said broken-up material layer (19) whereby the still heated but otherwise undisturbed old road surface enters into an intimate bond with the layers (19) and (25) in a single heat application.
