ABSTRACT:
Cationic aqueous bituminous emulsion-aggregate slurries are disclosed to be formed with cationic emulsions prepared at elevated temperatures by emulsifying bitumen, such as an asphalt, in water with a cation-active emulsifier which is the blend of the reaction of a polyamine or of a modified polyamine with certain polycarboxylic acids and glycol esters. The emulsifiers are obtained by reacting suitable polyalkylene amines with lignin and maleinized lignin or their blends with tall oil fatty acids and the reaction product of C.sub.8 -C.sub.15 alkylphenol with 30 to 100 moles of ethylene oxide.
