Problems solved by technology

[0005] The existing epoxy asphalt pavement materials use polytetrafluoroethylene rubber and polyvinyl difluoride to increase the high and low temperature resistance, corrosion resistance, aging resistance and toughness of the asphalt mixture, and add polyvinyl chloride fiber Improve the aging resistance, wear resistance, and moth resistance of pavement materials, and use nickel phosphate, silicon carbide and kaolin to improve the high temperature resistance and fracture resistance of pavement materials, but the existing epoxy asphalt pavement materials need to be exposed to high temperatures in summer It can only be constructed under the environment, and the improvement effect of epoxy resin on the early strength of asphalt is not obvious, and the curing time is long. After the construction is completed, it needs to be closed for a long time before opening to traffic

Abstract

The invention discloses a composite epoxy asphalt pavement material and a preparation method thereof. The composite epoxy asphalt pavement material comprises, by weight, 23.5-45.5 parts of modified epoxy resin, 40-60 parts of petroleum asphalt, 30-50 parts of basalt coarse aggregate, 15-25 parts of limestone mineral powder, 10-15 parts of cement, 5-10 parts of a plasticizer, 5-10 parts of a composite compatibilizer and 5-10 parts of a curing agent; and the curing agent is prepared from, by weight, 3.6-5.8 parts of tung oil anhydride, 2.2-3.4 parts of 2-methyl-4-ethylimidazole, 1.2-2.6 parts of4,4'-diaminodiphenylsulfone and 2.8-3.6 parts of polyamide acid. The composite epoxy asphalt pavement material has the advantages of short curing time, high early strength, shortening of the trafficopening time, absorbing of automobile exhaust, purifying of air and reduction of air pollution.

Description

technical field [0001] The invention relates to the technical field of pavement pavement materials, more specifically, it relates to a composite epoxy asphalt pavement material and a preparation method thereof. Background technique [0002] With the development of my country's transportation industry, higher and higher requirements are put forward for the technical performance of road asphalt materials. Various modified asphalts have emerged, such as adding rubber, resin, sulfur and other high polymers to asphalt to improve the road performance of asphalt concrete. Among them, thermosetting material modified asphalt introduces thermosetting The reactive group endows the material with excellent properties, such as high temperature stability, fatigue performance, solvent resistance, etc. Currently, thermosetting materials used in modified asphalt include epoxy resin, polyurethane, phenolic resin, acrylic acid, etc. [0003] Among them, the epoxy asphalt prepared by epoxy resi...
