Overview – VG30 Viscosity Grade Bitumen
VG30 is a high-viscosity paving grade bitumen engineered for use in high-traffic roads and heavy-duty applications. This grade is ideal for areas with hot climates and intense vehicular load, offering superior resistance to deformation and rutting. The “VG30” classification refers to its viscosity range at 60°C, making it the preferred bitumen type for national highways, expressways, and airport runways.
Viscosity-Based Classification and Testing
Viscosity grade bitumen is classified by its resistance to flow under standardized conditions. VG30’s high viscosity ensures excellent performance in demanding conditions, especially under mechanical stress and elevated temperatures. Its properties are tested using Brookfield and Saybolt viscometers according to ASTM and IS:73 standards, ensuring reliable measurement of consistency at both 60°C and 135°C. This level of control provides confidence in mixing, pumping, and field performance.
Applications and Export Advantages
VG30 is used extensively in the construction of major roads, highways, and heavy-load zones that require enhanced stability and fatigue resistance. Its stiffness and durability make it an excellent choice for dense-graded asphalt, bituminous macadam, and surface dressing under heat and pressure.
