ROADGRIP Bitumen
Cationic Bitumen Emulsion
IS : 8887 : 2004 (ISI MARKED)
Description
Emulsified asphalt has been used for road development and waterproofing for many years. As a road material it finds application as a slurry seal for the surface layer, pot hole repair and as a bonding coat for subsequent layers.
We manufacture three different grades of Emulsions
- 1) Slow Setting (SS-1 & SS-2)
- 2) Medium Setting (MS)
- 3) Rapid Setting (RS-1 & RS-2)

Applications
- Rapid Setting (RS): Used in surface dressing, tack coat and patch repair work.
- Medium Setting (MS): Used in pre mix with less quantity of fine aggregates and pothole repair works.
- Slow Setting (SS): Used in Priming base course, premix with appreciable quantity of fine aggregates such as slurry seal and fog seal.
