Bitumen VG 40 is a Viscosity Grade Bitumen which is widely used in spraying applications such as surface-dressing and paving in a very cold climate. It is also used to manufacture bitumen emulsion and modified bitumen products.
Application of Bitumen Viscosity grade VG 40
VG-40 is used in highly stressed areas such as intersections, near toll booths and truck parking lots instead of 30/40 penetration grade. Because of higher viscosity, stiffer Bitumen mixes can be produced to amend resistance to shoving and other problems related to higher temperature and heavy traffic loads.
Bitumen VG 40 Specification
Kiapetro guarantees that the Bitumen VG40 is produced in compliance and conformity to International of Standard ASTM D3381-09, AASHTO M226-80 (2008) and IS 73:2006, also meets the requirements of the following specification.
