ABSTRACT:
A method of modifying a cationic bitumen emulsion by initiating coalescence by either (i) adding a specific chemical agent or (ii) physical reaction. The method included modifying the bitumen emulsion by combining a second emulsion with a primary emulsion having an aqueous phase to create a bimodal distribution.
