Claims22
A reinforcement mat comprising a first and second layer of fiber material, each of said layers of fiber material formed of a plurality of fibers or fiber sets that are spaced apart from one another and positioned generally parallel to one another, a plurality of fibers or fiber sets of said first layer of fiber material positioned non-parallel to a plurality of fibers or fiber sets of said second layer of fiber material, said first and second layers of fiber material connected together, a plurality of fibers or fiber sets of said first layer of fiber material, a plurality of fibers or fiber sets of said second layer of fiber material, or combinations thereof are at least partially coated with a layer of resin.
A method for repairing pavement comprising the steps of:
- a. applying at least one layer of a reinforcement mat onto a sub-base of a road or path or sidewalk, said sub-base including crushed stone, asphalt, bitumen, rocks, ceramic, crushed ceramic, or concrete, said reinforcement mat comprising a first and second layers of fiber material, each of said layers of fiber material formed of a plurality of fibers or fiber sets that are spaced apart from one another and positioned generally parallel to one another, a plurality of fibers or fiber sets of said first layer of fiber material positioned non-parallel to a plurality of fibers or fiber sets of said second layer of fiber material, said first and second layers of fiber material connected together, a plurality of fibers or fiber sets of said first layer of fiber material, a plurality of fibers or fiber sets of said second layer of fiber material, or combinations thereof are at least partially coated with a layer of resin;
- and,
- b. applying at least one layer of asphalt or bitumen material on top of said at least one layer of said reinforcement mat, said asphalt or bitumen material having a temperature of at least about 45° F.
