The invention relates to the technical field of road engineering construction, and provides an iron tailing road base material as well as a preparation method and application thereof. The iron tailing road base material provided by the invention comprises a betaine type amphoteric polymer surfactant, an alkyl quaternary ammonium salt cationic surfactant, lignin, cement, water and iron tailings. The iron tailing road base material provided by the invention effectively reduces the thickness of double electric layers among iron tailing particles, fills tailing sand pores, and increases the overall compactness and strength of a mixture. According to the iron tailing roadbed material provided by the invention, the amphoteric and cationic polymer surfactants are utilized, the strength of the roadbed material can be continuously improved, meanwhile, hydrophilic groups of the surfactants are partially consumed, the water stability is improved, the frost heaving sensitivity is reduced, the water ...
