ABSTRACT:
High float asphalt emulsions with high demulsibilities are prepared from asphalts ill-suited for prior art emulsifiers by mixing a combination of fatty acid and the reaction products of fatty acid with acrylic acid, methacrylic acid, fumaric acid, or maleic anhydride in the form of their alkali salts in the soap solution, and adding to the heated asphalt, prior to the emulsification step, reaction products of fatty acids with mono-, di-, and triethanol amine.
