The invention discloses a mesoporous molecular sieve modified anti-rutting agent and a preparation method thereof, wherein the anti-rutting agent comprises the following raw material components by weight: 45-55 parts of high-density polyethylene, 45-55 parts of low-density polyethylene, 10-30 parts of styrene-butadiene rubber, 10-30 parts of polypropylene, and 5-8 parts of a modified mesoporous molecular sieve, wherein the modified mesoporous molecular sieve is a mesoporous molecular sieve modified with aminosilane, mercaptosilane and hindered phenol type antioxidant, and the hindered phenol type antioxidant contains a carboxyl group. According to the present invention, with the anti-rutting agent, the rutting resistance and the low temperature performance of the asphalt concrete are significantly increased, and the anti-aging performance of the asphalt concrete is improved so as to prolong the service life of the road. 本发明公开了种介孔分子筛改性抗车辙剂及其制备方法。该抗车辙剂按重量份计包括以下原料组分：高密度聚乙烯45～55份；低密度聚乙烯45～55份；丁苯橡胶10～30份；聚丙烯10～30份
