A method of emulsifying asphalt using a polyamine polyoxide, preferably a diamine dioxide, as an emulsifier or co-emulsifier and an emulsion of asphalt, water and a polyamine polyoxide, preferably a diamine dioxide. The advantages of using a polyamine polyoxide as an emulsifier or co-emulsifier include its ability to provide superior cationic and anionic emulsions, and slow-setting emulsions at low use levels, and the excellent adhesion of the cured asphalt film. |
