Ratings
(0)

Viscosity grade bitumen is classified based on its viscosity at a specific temperature, ensuring consistency in its flow characteristics during application.

 

- Grades: VG-10, VG-20, VG-30, VG-40.

- Uses:

  - VG-10: Suitable for spraying applications like surface dressing and cold climates.

  - VG-20: Ideal for regions with mild weather, used in pavement construction.

  - VG-30: Commonly used in hot climates for road construction and surfacing.

  - VG-40: Suitable for heavy traffic areas and industrial applications.

- Benefits: Viscosity grade bitumen provides better control over the quality of the asphalt mix and is more reliable in extreme temperatures, reducing the risk of pavement distress.
