VISCOSITY GRADE
Indian Standard – VG 10
Optimal Choice for Road Construction
Viscosity Grade Bitumen 10, or VG 10, is renowned for its extensive use in road construction due to its adaptability and effectiveness in various climate conditions, especially in cooler environments. Known for its superior binding characteristics and durability, VG 10 is essential for creating and maintaining long-lasting road surfaces.
Why Choose Bitumen VG 10?
VG 10 bitumen is favored for various road construction and maintenance tasks due to its distinct properties:
High Adhesiveness: VG 10 provides strong adhesion to aggregates, reinforcing the structural integrity of pavements.
Water Resistance: Its waterproof qualities protect underlying layers from water damage, thereby extending the pavement’s life.
Flexibility: VG 10 remains flexible at lower temperatures, minimizing the risk of cracks and deformation in colder climates.
Durability: With its excellent binding ability and resilience, VG 10 ensures that pavements can endure diverse loads and environmental conditions for extended periods.
Key Uses of Bitumen VG 10:
VG 10 bitumen is primarily employed in road construction and upkeep. Its lower viscosity is particularly advantageous in colder climates, ensuring that it remains workable even in lower temperatures. Here’s how VG 10 is commonly utilized:
Surface Dressing and Top Layers: VG 10 is frequently used in surface dressing techniques, where a bituminous binder is applied to the road surface followed by an aggregate layer. This process boosts the skid resistance and waterproof qualities of the road.
Penetration Macadam: This method involves spraying VG 10 bitumen over compacted aggregate layers to form a resilient and durable road structure.
Asphalt Pavements in Cold Climates: VG 10 is perfect for asphalt pavements in cooler areas, where more viscous bitumen would be too stiff.
Repair and Maintenance: VG 10’s excellent adhesion properties make it ideal for patching and repairing existing pavements, enhancing their lifespan and durability.
Technical Specifications
VG 10 bitumen adheres to rigorous technical standards, ensuring consistent performance and quality. The key specifications include:
Penetration Value: VG 10 features a penetration value ranging from 80-100, reflecting its softer consistency compared to higher viscosity grades.
Viscosity: At 60°C, VG 10 bitumen has a viscosity of 800-1200 poise, suitable for cooler climates and ease of application.
Softening Point: VG 10 typically has a softening point around 40-45°C, maintaining stability and effectiveness in lower temperatures.
Ductility: VG 10 demonstrates high ductility, allowing it to stretch and adapt without breaking, essential for coping with traffic loads and temperature variations.
