High-strength wear-resistant recycled asphalt mixture and preparation method thereof

The invention relates to a high-strength wear-resistant recycled asphalt mixture. The high-strength wear-resistant recycled asphalt mixture is prepared from a recycled old asphalt material, a new asphalt material, 3-hydroxy-5-phenyl-2-cyclohexene-1-ketone, 1-ethyl-2-methyl-5-cyanobenzimidazole, magnesium hydrogen sulfate, diethyl ether, a cross-linking agent, an initiator, tungsten disulfide, mineral powder and a regenerant, the invention further discloses the preparation method of the high-strength wear-resistant recycled asphalt mixture. In the application, an N-substituted amide product obtained by reaction of 3-hydroxy-5-phenyl-2-cyclohexene-1-ketone and 1-ethyl-2-methyl-5-cyanobenzimidazole can form a relatively strong hydrogen bond network effect, the molecular aggregation degree is increased, and the N-substituted amide product reacts with asphalt in the presence of an initiator and a cross-linking agent to form a new chemical bond, so that the molecular aggregation degree is increased, and the molecul
