Abstract: The present invention relates to the technical field of road engineering construction and relates to a red mud-based composite asphalt anti-aging agent, and a preparation method therefor and use thereof. The red mud-based composite asphalt anti-aging agent consists of the following raw materials in parts by weight: 100 parts of red mud, 20-40 parts of a nano material, 10 parts of a cationic surfactant and 1 part of a silane coupling agent. The cationic surfactant is hexadecyl trimethyl ammonium bromide or octadecyl trimethyl ammonium bromide. The red mud-based composite anti-aging agent prepared by the present invention is added into asphalt to prepare a modified asphalt mortar so as to remarkably improve the anti-aging ability of the asphalt and realize the functional comprehensive utilization of the red mud. The problem that the addition of the red mud may lead to insufficient water stability of an asphalt mixture at present is solved.
