Asphalt emulsion is an important component in the preparation of cement asphalt mortar. In the work reported here, different emulsifiers and basic asphalts were used to manufacture emulsions and their properties were investigated. Results indicate that a diamine-based emulsifier renders asphalt emulsion that exhibits better compatibility with cement; lower density and higher ductility basic asphalt; and that styrene-butadiene-styrene modifiers are more appropriate in the manufacturing of emulsion.
