A method of making a bituminous emulsion in which a fatty acid is mixed with a water solution of a base to form a water dispersion of said acid. Said dispersion is mixed with an aminoethyl substituted imidazoline to form a water soluble salt of said aminoethyl substituted imidazoline and acid. The salt is dissolved in water and then mixed in an emulsifying mill with a petroleum bitumen, said salt being added to the bitumen in an amount of from about 0.5% to about 2% based upon the weight of the bitumen. |
