Abstract

The invention discloses a resin type bio-based high-viscosity adhesive material for an anti-skid wearing layer pavement and a preparation method of the resin type bio-based high-viscosity adhesive material, and belongs to the technical field of road engineering materials. The resin type bio-based high-viscosity glue material for the anti-skid wearing layer pavement is prepared from the following raw materials: asphalt, vulcanized rubber powder, a resin matrix, a tackifier, a curing agent, a plasticizer, an antioxidant, a heat stabilizer and an auxiliary agent. Wherein the asphalt is a mixture of plant asphalt, coal asphalt and petroleum asphalt; the resin matrix is a mixture of polyurethane resin, epoxy resin, a polystyrene-butadiene copolymer, 2-methylpropyl methacrylate and a polymer of styrene and 2-ethylhexyl acrylate. The high-viscosity glue provided by the invention not only remarkably improves the bonding capacity of the resin type bio-base of the prefabricated pavement and the original road surface, but also greatly improves the wear resistance, weather resistance, high cohesiveness and toughness of the material, and remarkably improves the pavement performance of the resin type bio-base of the prefabricated pavement.
