What is Bitumen VG 30?

Bitumen VG 30, also known as Viscosity Grade 30 bitumen, is a widely used binder in road construction projects. The “VG” stands for Viscosity Grade, a modern classification system that defines bitumen based on its viscosity at specific temperatures. In the case of VG 30, the number indicates a viscosity range ideal for moderate to warm climates and heavy traffic loads.

Uses and Applications

Heavy-Duty Road Construction: Bitumen VG 30 excels in constructing pavements designed to withstand significant traffic volume and weight.

Hot Mix Asphalt (HMA): VG 30 bitumen is a primary component in HMA, ensuring proper mixing and application during the paving process.

Moderate and Warm Climates: VG 30’s viscosity characteristics offer optimal performance throughout the year.

Benefits of Using Bitumen VG 30

• Superior Durability: Longer-lasting roads with reduced maintenance costs.
• Excellent Load-Bearing Capacity: Handles heavy traffic loads without cracking.
• Versatility in Applications: Suitable for highways, industrial zones, and urban roads.
