Application of Environmentally Friendly Resin Asphalt Composite System in Steel Bridge Deck Pavement
The construction of steel deck pavement is a key and difficult point in the construction of steel box girder bridges.In order to explore an efficient and applicable construction technology of steel deck pavement,taking a river crossing highway bridge as an example,an environmentally friendly resin asphalt composite pavement scheme is proposed,and the construction control points of epoxy bonded macadam layer,resin asphalt concrete layer,SMA-13 asphalt concrete layer are analyzed and discussed.The results indicate that the setting of epoxy bonded crushed stone layer can effectively solve the corrosion prevention of steel bridge deck slabs and enhance the bonding of the pavement layer.The resin asphalt concrete layer can protect the epoxy adhesive material from high temperature and load damage of the upper concrete layer.SMA-13 high viscosity modified asphalt concrete layer can provide a better driving environment for the bridge deck.
