General description of emulsion Bitumen CRS, CRS1 & CRS2 ,RS
Bitumen CRS are usually made by passing the mixture of hot bitumen and water phase between a rotating disc, cone or wheel and a stator. In the emulsification process, hot binder is mechanically separated into minute globules and dispersed in water treated with a small quantity of emulsifying agent. The water is called the continuous phase and the globules of binder are called the discontinuous phase.by proper selection of an emulsifying agent and other manufacturing controls, emulsified asphalts are produced in several types and grades:
By choice of emulsifying agent, the emulsified asphalt may be:
(1) anionic – binder globules are electro-negatively charged.
(2) Cationic – binder globules are electro-positively charged. Also, by variation in materials and manufacture emulsified asphalts of both anionic and cationic types are made in several grades.
