Bitumen VG-40
BITUMEN VG-40
VG-40 is used in highly stressed areas such as intersections, near toll booths and truck parking lots instead of 40/50 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.
