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:
BS group Bitumen Emulsion CQS-1h is a cationic asphalt emulsion designed for use in slurry seals and micro-surfacing projects. BS group asphalt emulsions CQS-1h has minimum 62% bitumen and it is in chocolate brown in color and is a free flowing liquid at ambient temperature.
BS group Bitumen Emulsion CMS-2h is a cationic medium setting bitumen emulsion that contains 65% bitumen. Asphalt Emulsion CMS-2h is specially designed water based Bitumen Emulsion with moderate viscosity and setting time.
BS group Bitumen Emulsion MS-2K/ CMS-2 is medium setting which containing minimum 65% Bitumen. Asphalt Emulsion CMS-2 is specially designed water based Bitumen Emulsion with moderate viscosity and setting time.
BS group bitumen emulsion CSS-1h is a cationic slow setting bitumen emulsion that contains 57% bitumen. Emulsified asphalt CSS-1h is 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.
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.
BS group Bitumen Emulsion CRS2 is specially designed water based Bitumen Emulsion with high viscosity and fast setting time that makes it an ideal spraying product for road maintenance.
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.
BS group bitumen emulsion K3 is a mixture of water & bitumen, Addition of emulsifier with water facilitates breaking of bitumen into minute particles, K3 is a cationic (slow setting) road emulsion that contains 56% bitumen.
BS group bitumen emulsion K2 is a cationic emulsion that contains 57% bitumen. In fact, K2 is a cationic medium setting emulsion as per British standards and it’s suitable for premix – carpet and pothole repair.
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.
BS group asphalt emulsion K1-40 cationic bitumen emulsion is an emulsified asphalt containing minimum 40% bitumen and 60% water. It is a low viscosity emulsion used mainly for tack coating. Bitumen emulsion K1-40 is in chocolate brown in color and is a free flowing liquid at ambient temperature.
Bituminous asphalt emulsion K1-60 is a rapid setting cationic asphalt, which has positive charge leading reaction between the emulsion and pavement. It contains 57% bitumen. 1 denoted as rapid braking. The primer bitumen which is used for emulsification is obtained from crude oil.
