  • Patent number: 5964549
    Abstract: An apparatus for repairing a crack in a bituminous road surface utilizes a beam embedded in the road surface. A slot is cut in the road with the crack centered therein. A fiber reinforced plastic composite beam has a plurality of fingers extending from one end thereof. The beam is placed on a sand base in the slot with a straight end of the beam on one side of the crack and a serrated/finger end on the opposed side of the crack. A panel having apertures therein is positioned over the finger end of the crack. A course aggregate material is placed atop the sand base within epoxy material then filling the slot so as to anchor the beam therein. Upon curing, the road material is placed atop the beam and flush with the original road surface. The fingers are coated with a release agent to preclude binding with the surrounding epoxy material which allows for movement of the beam relative to the surrounding material upon forces acting upon the beam.
