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.
Typical properties of CRS1
BS group Bitumen Emulsion CRS1 is manufactured strictly as per ASTM D2397-13
AASHTO M208-16 or IS 8887: 2004.

Advantages
At the following you can find some advantages of this product:
- Environment friendly
- No heating required
- Cost efficient
- Easy and uniform spray
- Low temperature curing, fast setting time
- High adhesive properties
- Prevents slippage of structural layers
Applications
Main application of CRS asphalt emulsion is using for surface treatment projects as:
- Single surface treatment
- Multiple surface treatment
- Sand seal
BS group Bitumen Emulsion CRS1 is ideally suited for Tack Coat application as well and other applications will see below:
- To ensure a proper bond between existing surface and the new bituminous course being placed over it.
- To ensure longevity of the road, it is important that the new bituminous surface bonds firmly with underneath surface
- To coat and bond loose mineral particle on the surface of the surface layer
- To seal surface pores and make the surface water-resistant
- To impart structural stability and prevent lateral movement of layer
- To assist adhesion between the base and super impose surface course
Tack coat application is a light spray of Bitumen Emulsion, which may be hand or machine sprayed. It is used to ensure a good bond between an old and a new bituminous surfacing layer. It is normally applied very thin and evenly over the entire surface.
