Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
91 words
A pavement mat comprising a fibrous mat impregnated with a mixture of bituminous material and aggregate, said mat having a wear surface and bottom surface, a bituminous adhesive layer extending along said bottom surface, a particulate inorganic release coating on said adhesive layer for preventing said mats from adhering to one another when stacked one on top of the other, bottom surface to wear surface, said release coating being forced into said adhesive surface by pressure applied to said wear surface when said mat is in place on a road surface.
Claim 2
Dependent Claim
91 words
A pavement mat comprising a fibrous mat impregnated with a mixture of bituminous material and aggregate, said mat having a wear surface and bottom surface, a bituminous adhesive layer extending along said bottom surface, a particulate inorganic release coating on said adhesive layer for preventing said mats from adhering to one another when stacked one on top of the other, bottom surface to wear surface, said release coating being forced into said adhesive surface by pressure applied to said wear surface when said mat is in place on a road surface.
Claim 3
Dependent Claim
29 words
The pavement mat of claim 1 where said release coating is selected from at least one member of the group consisting of a silicon dioxide material and a clay.
Claim 4
Dependent Claim
16 words
The pavement mat of claim 2 where said silicon dioxide comprises a finely divided silicon dioxide.
Claim 5
Dependent Claim
256 words
A process for the surfacing of a pavement comprising delivering a plurality of adhesive backed pavement mats on a first vehicle to a road surface, said road surface selected from at least one member of the group consisting of bituminous, concrete and metal surfaces, said plurality of mats being stacked one on top of the other, bottom surface to wear surface placing one end of the top mat in said plurality on said road surface so that said adhesive back is in contact with said road and securing said end so placed by a second wheeled vehicle, said second wheeled vehicle being sufficiently heavy to bond said adhesive back to said road when said second vehicle is wheeled over said mat, moving said first vehicle forward until said mat is pulled off of said first vehicle, wheeling said second vehicle over said mat to bond said mat to said road surface, repeating said process until each mat of said plurality is applied to said road, said pavement mat comprising a fibrous mat impregnated with a mixture of bituminous material and aggregate, said mat having a wear surface and bottom surface, a bituminous adhesive layer extending along said bottom surface, a particulate inorganic release coating on said adhesive layer for preventing said mats from adhering to one another when stacked one on top of the other, bottom surface to wear surface, said release coating being forced into said adhesive surface by pressure applied to said wear surface when said mat is in place on a road surface.
Claim 6
Dependent Claim
256 words
A process for the surfacing of a pavement comprising delivering a plurality of adhesive backed pavement mats on a first vehicle to a road surface, said road surface selected from at least one member of the group consisting of bituminous, concrete and metal surfaces, said plurality of mats being stacked one on top of the other, bottom surface to wear surface placing one end of the top mat in said plurality on said road surface so that said adhesive back is in contact with said road and securing said end so placed by a second wheeled vehicle, said second wheeled vehicle being sufficiently heavy to bond said adhesive back to said road when said second vehicle is wheeled over said mat, moving said first vehicle forward until said mat is pulled off of said first vehicle, wheeling said second vehicle over said mat to bond said mat to said road surface, repeating said process until each mat of said plurality is applied to said road, said pavement mat comprising a fibrous mat impregnated with a mixture of bituminous material and aggregate, said mat having a wear surface and bottom surface, a bituminous adhesive layer extending along said bottom surface, a particulate inorganic release coating on said adhesive layer for preventing said mats from adhering to one another when stacked one on top of the other, bottom surface to wear surface, said release coating being forced into said adhesive surface by pressure applied to said wear surface when said mat is in place on a road surface.
Claim 7
Dependent Claim
95 words
The process of claim 4 where said pavement mat comprises a fibrous mat impregnated with a mixture of bituminous material and aggregate, said mat having a wear surface and bottom surface, a bituminous adhesive layer extending along said bottom surface, a release coating on said adhesive layer for preventing said mats from adhering to one another when stacked one on top of the other, bottom surface to wear surface, said release coating being forced into said adhesive surface by pressure applied to said wear surface when said mat is in place on a road surface.
Claim 8
Dependent Claim
28 words
The process of claim 4 where said release coating is selected from at least one member of the group consisting of a silicon dioxide material and a clay.
Claim 9
Dependent Claim
15 words
The process of claim 6 where said silicon dioxide comprises a finely divided silicon dioxide.
