Asphalt is heated to a temperature within the range from about 375.degree. F. to about 400.degree. F. and subsequently rapidly admixed with an aqueous slurry of hydrophilic clay in a manner and in proportions which achieve heat transfer from asphalt to clay slurry without excessive water evaporation to provide the desired emulsification.
