Cationic bitumen emulsion

CRS 1, CRS 2, CSS1, CSS-1h, CQS-1h, CMS2, CMS-2h, k2,k3,k1-40,k1-60,k1-70

The Cationic Bitumen Emulsion is chocolate brown and free flowing at normal temperature. Once it breaks the bitumen breaks out and color changes to black. An Emulsion is said to break when the organic and the aqueous phase separate into two distinct layers i.e. the dispersion ceases to exist. Emulsions are classified as Rapid Setting-1(RS-1), Rapid Setting-2(RS-2), Medium Setting (MS), SlowSetting-1 (SS-1), Slow Setting-2 (SS-2). The breaking time varies according to the designation of Emulsion although being largely dependent upon the climatic condition i.e. temperature, humidity, wind velocity etc.

Cationic Bitumen Emulsion has been recommended to use in several applications of Road Work like Tack Coat, Prime Coat, Surface Dressing work, 20 mm Premix Carpet, Sealing of cracks with fog seal, slurry seal, micro surfacing etc.

BS group has been equipped by DenimoTech full automatic inline emulsion plant which is able to produce different bitumen emulsion grades with superior quality. Some of our cationic emulsions that are classified according ASTM and EN standards are here:

Bitumen Emulsion CSS1

BS group Bitumen Emulsion CSS-1 is cationic bitumen emulsion containing minimum 57% bitumen. It’s specially designed water based Bitumen Emulsion with low viscosity and extended setting time that makes it an ideal product for prime coating on high porous surfaces. It is dark brown in color and is a free flowing liquid at ambient temperature.


Bitumen Emulsion CRS1

BS group Bitumen Emulsion CRS1 is specially designed water based Bitumen Emulsion with low viscosity and fast setting that makes it an ideal product for Tack Coat spray application but one of the main application of CRS emulsion is surface treatment (Chip seal, sand seal and fog seal by cement curing). BS group asphalt emulsion CRS-1 contains 60% bitumen and it is chocolate brown in color and is a free flowing liquid at ambient temperature.


Bitumen Emulsion K1-70

BS group asphalt emulsion K1-70 is a cationic rapid setting bitumen emulsion that contains 67% bitumen. It is a medium viscosity emulsion used mainly for tack coating in normal overlay and patching work. Bitumen emulsion K1-700 is in chocolate brown in color and is a free flowing liquid at ambient temperature and is commonly used for Tack-Coating as well.
