    摘要: There is disclosed herein oil-in-water cationic bituminous emulsions of improved mechanical stability for mixing grade emulsions comprising, from about 30 to about 80% by weight bitumen, from 0.1 to about 10.0% by weight of a water-soluble quaternary amine of the reaction of epichlorohydrin, trimethylamine and an alkyl phenol, for example, nonyl phenol and dodecyl phenol, as the cationic active emulsifier for the bitumen and the remainder water. A marked degree of control is attainable over the break time and coating characteristics of coated aggregates by varying the amount of emulsifier. Additionally, auxiliary emulsifiers may be added to tailor the emulsions to the amount of fines or types of aggregates with which the emulsion may be used.
