Application of Bitumen emulsion Grades in Road Development, Construction & Maintenance
  • Rapid Setting (RS-1): It is recommended for tack coat applications
  • Rapid Setting (RS-2): It is recommended for surface dressing, grouting
  • Medium Setting (MS): It is used for repair work, surface dressing, penetration macadam
  • Slow Setting (SS-1): It is used for prime coat, crack sealing and fog seal
  • Slow Setting (SS-2): It is used for slurry seal, road mixes and for prime coat applications
