Viscosity Grade Bitumen
Viscosity-Controlled Binders for Asphalt Engineering
Viscosity Grade Bitumen is classified according to its flow resistance at specified temperatures and is used in asphalt production and pavement construction.
| Grade | Absolute Viscosity at 60°C (Poise) | Kinematic Viscosity at 135°C, Min. (cSt) |
|---|---|---|
| VG-10 | 800–1,200 | 250 |
| VG-20 | 1,600–2,400 | 300 |
| VG-30 | 2,400–3,600 | 350 |
| VG-40 | 3,200–4,800 | 400 |
Reference Standard:IS 73:2013
