VISCOSITY GRADE

Indian Standard – VG 40

Superior Solution for Heavy Traffic Roads

Indian Standard VG 40, often abbreviated as VG 40, is a premier grade of bitumen renowned for its high performance and durability in demanding road construction applications. Its superior binding properties and high viscosity make it particularly well-suited for heavy-duty road surfaces and environments with substantial traffic loads.

Why Choose Bitumen VG 40?

VG 40 bitumen is favored for its distinctive properties that enhance its suitability for heavy-duty road construction and maintenance:

Exceptional Adhesion: VG 40 bitumen provides superior adhesion to aggregates, ensuring a strong bond that reinforces the structural integrity of the pavement.
High Water Resistance: Its excellent waterproofing properties protect underlying layers from moisture, which helps to prolong the pavement’s service life.
Flexibility: VG 40 remains flexible under various temperatures, reducing the likelihood of cracks and deformation, which is essential for maintaining road quality in diverse conditions.
Durability: With its high binding strength and resilience, VG 40 is capable of withstanding heavy loads and extreme environmental conditions, offering long-term durability.

Key Uses of Bitumen VG 40:

VG 40 bitumen is predominantly utilized in the construction and maintenance of roads that require enhanced durability and load-bearing capacity. Its higher viscosity makes it ideal for high-traffic areas and regions with severe climatic conditions. Here are some of the key applications:

Surface Dressing and Top Layers: VG 40 is frequently used in surface dressing processes, where it acts as a binder on the road surface followed by the application of an aggregate layer. This improves the road’s skid resistance and waterproofing characteristics.
Penetration Macadam: VG 40 bitumen is applied in the penetration macadam technique, where it is sprayed over compacted aggregate layers to form a strong, durable road foundation.
High-Traffic Asphalt Pavements: VG 40 is especially effective for asphalt pavements in areas with heavy traffic and extreme environmental conditions, providing a resilient and stable road surface.
Heavy-Duty Repair and Maintenance: Due to its high binding strength, VG 40 is ideal for repairing and maintaining existing bituminous pavements, extending their lifespan and ensuring they can withstand intense traffic loads.

Technical Specifications

VG 40 bitumen meets stringent technical standards to ensure reliability and performance. Key specifications include:

Penetration Value: VG 40 has a penetration value of 10-20, indicating a firmer consistency compared to VG 10, VG 20, and VG 30, making it suitable for high-load applications and demanding conditions.
Viscosity: At 60°C, VG 40 bitumen has a viscosity range of 5000-8000 poise, ensuring it can handle heavy traffic and extreme conditions while maintaining ease of application.
Softening Point: The softening point of VG 40 is typically between 60-70°C, providing stability and effective performance across a broad range of temperatures.
Ductility: VG 40 demonstrates high ductility, allowing it to endure significant stress without breaking, which is crucial for withstanding heavy traffic and environmental changes.
