VISCOSITY GRADE

Indian Standard – VG 30

Premier Choice for Heavy-Duty Road Construction

Indian Standard VG 30, or VG 30, is a widely recognized grade of bitumen renowned for its durability and high performance in various road construction applications. Its robust binding properties make it an essential material for constructing long-lasting road surfaces, particularly in regions with diverse climatic conditions.

Why Choose Bitumen VG 30?

VG 30 bitumen is selected for its distinctive features that make it a top choice for heavy-duty road construction and maintenance:

Strong Adhesion: VG 30 bitumen offers exceptional adhesion to aggregates, forming a strong bond that enhances the overall structural integrity of the pavement.
High Water Resistance: The bitumen’s waterproof properties protect underlying layers from moisture damage, contributing to the pavement’s extended lifespan.
Flexibility: VG 30 remains flexible under a range of temperatures, reducing the risk of cracks and deformation, which is crucial for maintaining road quality in diverse climates.
Durability: With its high binding strength and resilience, VG 30 ensures that pavements can handle heavy loads and varying environmental conditions, providing long-term durability

Key Uses of Bitumen VG 30:

VG 30 bitumen is primarily used in the construction and maintenance of roads. Its higher viscosity makes it ideal for a variety of environments, especially where enhanced load-bearing capacity and durability are required. Common applications include:

Surface Dressing and Top Layers: VG 30 is extensively used in surface dressing operations, where it is applied as a binder on road surfaces followed by an aggregate layer. This enhances the road’s skid resistance and water resistance.
Penetration Macadam: In the penetration macadam method, VG 30 bitumen is sprayed over compacted aggregate layers to create a robust and enduring road structure.
Asphalt Pavements in Diverse Conditions: VG 30 is particularly well-suited for asphalt pavements in regions with varying temperatures and heavy traffic conditions, providing a stable and resilient surface.
Repair and Maintenance: Due to its superior binding qualities, VG 30 is effective for patching and repairing existing bituminous pavements, which helps in prolonging their service life and ensuring durability.

Technical Specifications

VG 30 bitumen adheres to strict technical standards to ensure consistent quality and performance. Key specifications include:

Penetration Value: VG 30 has a penetration value of 20-30, indicating a firmer consistency compared to VG 10 and VG 20, suitable for heavier traffic and more demanding applications.
Viscosity: At 60°C, VG 30 bitumen has a viscosity range of 3000-5000 poise, making it well-suited for high-load applications and varying environmental conditions.
Softening Point: VG 30 typically has a softening point between 55-65°C, maintaining stability and performance under a range of temperatures.
Ductility: VG 30 exhibits excellent ductility, allowing it to stretch and adapt under stress without breaking, which is essential for enduring traffic loads and temperature fluctuations.
