Properties & Benefits
Viscosity grade bitumen is a variety of bitumen classified primarily by its viscosity—its resistance to flow—measured at specific temperatures (typically at 60°C and 135°C). Following are the properties of viscosity grade bitumen:
Thermoplastic Nature
VG bitumen softens at high temperatures and hardens at lower temperatures, allowing it to adapt to varying climatic conditions
Viscosity
Defined as the resistance to flow, measured at 60°C and 135°C. Higher VG numbers indicate higher viscosity and greater hardness
Penetration Value
Indicates hardness; lower penetration means harder bitumen. For example, VG 30 has a penetration value of 50–70 (0.1 mm) at 25°C
Softening Point
The temperature at which bitumen softens; higher VG grades have higher softening points, making them suitable for hotter climates
Ductility
Measures the ability to stretch without breaking. VG 30, for instance, typically has ductility of 100 cm at 25°C
Flash Point
Indicates the temperature at which vapors ignite; VG bitumen generally has a flash point above 220°C, ensuring safety during handling
Applications
supplied viscosity grade bitumen is suitable for applications like road construction, building construction, industrial uses, and other paved surfaces.
Following are the applications of supplied viscosity grade bitumen:
VG 10 finds application in surface dressing in regions with cold/moderate temperature conditions
VG 30 finds application in dense bituminous macadam, binder and wearing courses, and moderate climates
VG 40 finds application in highways and roads with heavy traffic in regions with hot climates
