Asphalt emulsion CRS-2 is a cationic rapid setting bitumen emulsion that contains 65% bitumen, is black in color and is manufactured strictly as per ASTM D 2397M-13 standard.
Bitumen Emulsion CRS-2 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, the 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 the binder are called the discontinuous phase.by proper selection of an emulsifying agent and other manufacturing controls.
Application of Bitumen Emulsion CRS-2
Bitumen Emulsion CRS-2 Used for penetration macadam, grouting and surface dressing.
