Abstract

The invention discloses a heat-resistant and waterproof epoxy asphalt pavement material. The heat-resistant and waterproof epoxy asphalt pavement material is composed of raw materials including, by weight part, 50 parts of petroleum asphalt, 12-18 parts of polyvinylidene fluoride rubber, 10-15 parts of epoxy resin, 5-9 parts of tetrafluoroethylene-ethylene-ethyl acetate copolymer, 1-3 parts of adipic acid, 3-7 parts of polysebacic polyanhydride, 4-7 parts of hydroxyethyl methylperfluorocaprate, 1-4 parts of a promoter and 10-14 parts of a filler, The heat-resistant and waterproof epoxy asphaltpavement material improves the internal structure microscopically by optimizing special asphalt formulation; the polyvinyllidene fluoride rubber, the epoxy resin and the tetrafluoroethylene-ethylene-ethyl acetate copolymer can enhance the heat-resistant and waterproof performance and the tenacity of mixed asphalt materials; added polylactide filaments can improve the aging-resistant, wear-resistant and corrosion-resistant performances of the heat-resistant and waterproof epoxy asphalt pavement material; boron nitride, zinc oxide and niobium oxide are reasonably proportioned to maximize the heat-resistant and waterproof performances of the heat-resistant and waterproof epoxy asphalt pavement material.

Description

technical field [0001] The invention relates to a pavement material and a preparation method thereof, in particular to a heat-resistant and waterproof epoxy asphalt pavement material and a preparation method thereof. Background technique [0002] Asphalt pavement is a widely used pavement material. Asphalt materials can resist the damage caused by vehicles and pedestrians to the road surface, making the road surface more smooth, durable and waterproof. There are many applications on urban arterial roads, highways and other roads. In the prior art, asphalt pavement materials have the disadvantages of poor heat resistance and poor waterproof effect, and the variability is prone to rutting. Contents of the invention [0003] In view of the above deficiencies, the purpose of the present invention is to develop a heat-resistant and waterproof epoxy asphalt pavement material. By optimizing the asphalt formula, the internal structure of the asphalt can be improved on a microscop...
