* Conforms to (IS 73:2006) Specifications.

Usage: Bitumen VG-40 is used in highly stressed areas such as: Intersections, Air ports, truck parking lots, near toll booths and roads with heavy traffic loads in higher temperatures. Because of higher viscosity it also can be used instead of 30/40 bitumen penetration grade.
