Viscosity Grade Bitumen
Description
Viscosity-graded bitumen is evaluated based on its flow properties at specific temperatures, rather than its penetration. This grading system is highly accurate, making it suitable for precise engineering applications.
Grades
VG10, VG20, VG30, and VG40, with VG10 being the softest and VG40 the hardest.
Applications
Primarily used in hotter regions where roads experience high traffic. VG grades are also common in surface dressing and asphalt mixes requiring high viscosity stability.
