Abstract

The invention discloses a composite epoxy asphalt pavement material, which comprises the following materials in parts by weight: 50 parts by weight of petroleum asphalt; 12-18 parts by weight of polytetrafluoroethylene rubber; 10-15 parts by weight of epoxy resin; poly 1,1 -Difluoroethylene 5-9 parts by weight; octadecyl vinyl ether 1-3 parts by weight; polysebacic anhydride 3-7 parts by weight; accelerator 1-4 parts by weight; filler 10-14 parts by weight. By optimizing the formula of special asphalt, the internal structure of asphalt is improved at a microscopic level, and the addition of polytetrafluoroethylene rubber, epoxy resin and polyvinylidene fluoride can effectively increase the high and low temperature resistance of asphalt mixture, Corrosion resistance, aging resistance and toughness, the added polyvinyl chloride fiber improves the aging resistance, wear resistance, corrosion resistance and moth resistance of the pavement material, and the reasonable compatibility of nickel phosphate, silicon carbide and kaolin makes the pavement material high temperature resistant Performance and fracture resistance to achieve the best.

Description

technical field [0001] The invention relates to a pavement material and a preparation method thereof, in particular to a composite 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 being easy to soften at high temperature and easy to break at low temperature, and are not resistant to corrosion and are easy to age. Contents of the invention [0003] In view of the above-mentioned deficiencies, the purpose of the present invention is to develop a composite epoxy asphalt pavement material. By optimizing the asphalt formula, the internal structure of the asphalt can be improved...
