Bituminous Road Emulsion

Bitumen is highly viscous material, not workable at ambient temperatures. One of the best ways to make it workable is to emulsify it with water to obtain Bitumen emulsion which is workable in wide range of temperatures. Emulsion is defined as a mixture of two immiscible liquids one of which is dispersed in the other in the form of very fine particle. The process of emulsification is accomplished by use of an emulsifier and a stabilizer. A Colloid mill is generally used for preparation of emulsion.
