Abstract: An epoxy mortar material for a bridge expansion joint structure and a construction method. The epoxy mortar material includes a liquid A, a liquid B and a filler, wherein diamines D2000 and D230 are mixed to act as the epoxy resin curing agent. The curing agent has low viscosity, good compatibility with epoxy resin, long usable life, high bonding strength, and good flexible and heat shock resistance, so that it is suitable for the epoxy mortar material capable of absorbing the stress. Furthermore, the silicone adhesive is made into the sealing waterstop band, so that the present invention has good water resistant performance; the color of the expansion joint structure is the same as that of the adjacent concrete or asphalt, so that the bridge has beautiful appearance; the expansion joint structure has no tremors while vehicles passing through, noise generated by vehicle driving is lower.

Abstract: A high-permeability epoxy waterproof coating material includes a first fluid and a second fluid. The first fluid by mass percentage includes 50-75% bisphenol A epoxy resin, 5-15% reactive diluent, 10-20% epoxy resin toughening agent, and 20-40% benzene diluent. The second fluid by mass percentage includes 15-20% polyether amine D2000, 10-15% D230, 50-70% diluent, 2-5% accelerant, and 20-30% benzene diluent. The first fluid is mixed with the second fluid to obtain the coating material. The coating material has strong permeability and good flexible, and is able to penetrate and repair surface cracks and pores of the concrete, for forming a layer of sealed integral waterproof structure on the concrete surface. Even if the surface film forming material is destroyed, the concrete surface is also closed by the coating, so as to form the dense waterproof structure, thereby achieving the permanent water proofing.
