Application of bituminous as emulsions is so simple. It needs no heat, solvent and reagent. Only, it needs to add more water to adjust its parameters, like viscosity. In this research, the effects of different parameters have been studied on viscosity of five groups (MS-1, MS-2, MS-2h, SS-1, and SS-1h) of anionic bituminous emulsions (ASTM D977), and a simple nonlinear equation have been fitted to experimental viscosity data. The base of bituminous was Asmari Ahwaz Crude Oil. The anionic bituminous emulsions were produced by different mixture of sodium soap of Vinsol Resin, Arkopal N-60, Bentonite and tap water as oil in water emulsions. In this research, the effects of internal phase ratio, internal phase penetration, and the ratio of emulsifier have been studied on viscosity of emulsion.
