VG 20
VG 20 is a viscosity grade paving bitumen to the Indian standard IS 73, with an absolute viscosity of 1600–2400 poise at 60°C. Viscosity grading gives road engineers a direct link between the binder and its performance at peak pavement temperature.
Where VG 20 is used
Viscosity grade bitumen is classified by its viscosity at 60°C — the maximum pavement temperature — which predicts rutting performance more reliably than penetration alone.

Storing VG 20
Temperature: Keep paving grades between roughly 140°C and 170°C in working tanks, and store at the lower end for long holds. Avoid repeated heat-up and cool-down cycles.
Tanks: Use insulated, heated steel tanks with a closed vent system. Dedicate a tank to one grade, or clean it fully between grades to avoid cross-contamination.
Safety: Water and hot bitumen must never meet, because it causes violent foaming. Use heat-resistant PPE, and keep a dry, ventilated area with no ignition sources near the vents.
Shelf life: Bitumen hardens slowly under prolonged heat. Rotate stock, avoid holding it at peak temperature, and re-test before use after long storage.
