ABSTRACT:
A pavement mat is disclosed comprising a fibrous mat impregnated with a bituminous material and an aggregate. The bottom layer of the mat has an adhesive such as an asphalt base adhesive on it whereas the top layer comprises a wear surface. A release coating such as rock or slate dust is applied to the adhesive so that the mats may be stacked one on top of the other without sticking to one another, the release coating also being forced into the adhesive when the mat is placed on a road surface which has been prepared by being swept and sprayed with a solvent (i.e., kerosene or No. 2 fuel oil) so that the adhesive layer may be bonded to the road surface.
A process for resurfacing a road with such mats is disclosed comprising placing a plurality of mats on a first vehicle and partially removing one of the mats from the vehicle by means of chain attached to an anchor vehicle and to the mat with spring clamps so that a relatively small portion of the adhesive surface of the mat is placed on the road surface. A second vehicle is wheeled onto that portion of the mat that is placed on the road surface to hold the mat in place and the first vehicle is pulled forward until the entire mat is removed. The second vehicle is then wheeled over the mat that is completely on the road surface so that the mat is adhered and the process repeated until all of the mats are applied.
