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 product of the reaction of modified polyamine with certain polycarboxylic acids and anhydrides. The modified polyamines are obtained by reacting suitable polyalkylene amines with a sugar-containing syrup, preferably molasses.
