Different Grades of Bitumen available:
VG-10 BITUMEN:
- VG-10 is widely used in spraying applications such as surface-dressing and paving in very cold climates instead of the old 80/100 Penetration grade.
- It is also used to manufacture Bitumen Emulsion and Modified Bitumen products.
VG-20 BITUMEN:
- VG-20 is used for paving in cold climates & high-altitude regions
VG-30 BITUMEN:
- VG-30 is primarily used to construct extra heavy-duty Bitumen pavements that need to endure substantial traffic loads.
- It can be used instead of 60/70 Penetration grade.
VG-40 BITUMEN:
- VG-40 is used in highly stressed areas such as intersections, near toll booths, and truck parking lots instead of the old 30/40 Penetration grade.
- Due to its higher viscosity, stiffer Bitumen mixes can be produced to improve resistance to shoving and other problems associated with higher temperature and heavy traffic loads.
VG-50 Bitumen is not a grade of bitumen standardized.
