The present invention relates to a polymer concrete mortar composition for thin layer pavement for bridges comprising a methyl methacrylate (MMA)-based acrylic resin and fine aggregate of quenched steel slag, and a thin layer paving construction method for bridges using the same, and more particularly, to water, methyl methacrylate (MMA), 2-ethylhexyl acrylate (2-EHAM) and methacrylic acid (MAAC), a reactive emulsifier, a copolymerization initiator, an acrylic copolymer resin comprising an alkalizing agent and a peroxide curing agent The first subject (A) And, a second subject (B), which is a reinforcing resin containing an unsaturated polyester resin and a peroxide curing agent, and a silane-based coupling agent (C) as a crosslinking agent for increasing the chemical adhesion of polymer concrete. a binder; A polymer concrete mortar composition for thin layer pavement for bridge bridges comprising a methyl methacrylate (MMA)-based acrylic resin and quenching steel slag fine aggregate including; an inorganic binder including a fine aggregate of quenched steel slag having a particle size of 0.05 to 2 mm and a calcium carbonate filler, and It relates to the construction method of the thin layer pavement for the bridge surface used. The polymer concrete mortar composition for thin layer pavement for bridges of the present invention reduces the dead load of the pavement by making the thickness of the pavement thin, and the construction or repair of the pavement is easy, thereby reducing the construction cost and shortening the construction period. It has excellent performance and has the effect of improving the durability of the bridge. |
