Minute Bitumen particles dispersed in water is called Bitumen Emulsion. An Emulsion in which the cation of the emulsifier is at the interface with the bitumen particle: An Emulsion in which the particles are positively charged and the aqueous phase is acidic are called Cationic Emulsions.
UNIVERSAL Cationic Emulsions are manufactured and tested confirming to the specifications of IS 8887.
UNIVERSAL Bitumen Emulsion have advantages over hot applied bitumen. Cold applied Bitumen Emulsions is fulfilling a real technical and commercial requirement for roads. Bitumen Emulsions are used in road works due the reliability, economy and simplicity of application.
