Abstract:
Slurries are formed with cationic emulsions prepared by emulsifying bitumen, such as an asphalt, in water with a cation-active emulsifier which is the product of the reaction of polyamine with certain polycarboxylic acids, which product is subsequently modified by reaction with from 10-30% of a member of the group consisting of acetic anhydride, phthalic anhydride, propylene carbonate, and styrene oxide.
