According to FT-IR spectra, it was concluded that four kinds of emulsifier were prepared successfully. The properties (ultralow interfacial tension, foamability and contact angle) of the four emulsifiers were measured. Then choose the most appropriate one. The mass ratio of clay and asphalt and the dosage of emulsifier and suspending agent were determined by experiments, then prepared the clay asphalt composite suspension system. The results showed that octadecyl (2-sulfite) ethyl dimethyl
