  • Road reinforcement sheet, structure of asphalt reinforced pavement and method for paving road
    Patent number: 7232276
    Abstract: A paved road including a reinforcement sheet layer (1A) and a pavement layer (22), in which the reinforcement sheet layer (1A) includes an asphalt layer (2) laminated to at least one side of a reinforcement sheet (1) including a composite material that is impregnated with a thermoplastic resin to achieve a volume content of a continuous glass fiber, which is a reinforcement fiber, of not less than 30% and not moere than 85% is proved.
    Type: Grant

  • Laminated product having surface protection layer
    Patent number: 6764741
    Abstract: A laminated product according to the present invention has a fiber reinforced resin layer, an elastic layer laminated on one surface of the fiber reinforced resin layer, and a surface protection layer laminated on a surface of the elastic layer for protecting the surface of the elastic layer. The fiber reinforced resin layer includes at least two prepreg sheets, each of which is formed by impregnating a thermoplastic resin into continuous reinforcing fibers arrayed in one direction such that the volume ratio of the continuous reinforcing fibers is in the range of 40 to 80%. The prepreg sheets are laminated so as to the array directions of the continuous reinforcing fibers at right angles.

  • Road reinforcement street, structure of asphalt reinforced pavement and method for paving road
    Publication number: 20030086762
    Abstract: A paved road including a reinforcement sheet layer (1A) and a pavement layer (22), in which said reinforcement sheet layer (1A) includes an asphalt layer (2) laminated to at least one side of a reinforcement sheet (1) including a composite material that is impregnated with a thermoplastic resin so that a volume content of a continuous glass fiber is not less than 30% and not more than 85% using the continuous glass fiber as reinforcement fiber is provided. The paved road shows remarkably excellent durability to rutting and crack, and a thin surfacing (thin layer pavement) paving with thickness of asphalt made thinner becomes possible.
