VISCOSITY GRADE

Indian Standard – VG 20

Ideal for Robust Road Construction

Indian Standard VG 20, often referred to as VG 20, is a prominent choice in the realm of bitumen products due to its versatile application and robust performance across various environments. This grade of bitumen is celebrated for its excellent binding properties, making it a crucial component in the construction and upkeep of durable road surfaces.

Why Choose Bitumen VG 20?

VG 20 bitumen is selected for its specific attributes, which make it an excellent choice for numerous road construction and maintenance applications:

Strong Adhesion: VG 20 bitumen offers excellent adhesion to aggregates, ensuring a solid bond that strengthens the pavement’s structural integrity.
Effective Water Resistance: Its water-resistant properties safeguard the underlying layers from moisture infiltration, which helps in prolonging the pavement’s lifespan.
Flexibility: VG 20 maintains flexibility across a range of temperatures, reducing the likelihood of cracks and deformation, particularly in moderate climates.
Durability: The robust binding capabilities and resilience of VG 20 ensure that pavements constructed with this bitumen grade can endure varying loads and environmental conditions over time.

Key Uses of Bitumen VG 20:

VG 20 bitumen is predominantly utilized in road building and maintenance projects. Its moderate viscosity makes it suitable for a range of climates, including both moderate and cooler conditions. Here’s how VG 20 is commonly applied:

Surface Dressing and Top Layers: VG 20 is widely used in surface dressing processes, where it serves as a binder on the road surface, followed by the application of an aggregate layer. This technique enhances skid resistance and water resistance of the road.
Penetration Macadam: VG 20 bitumen is employed in the penetration macadam method, where it is sprayed over compacted aggregate layers to form a strong and durable road foundation.
Asphalt Pavements in Diverse Climates: VG 20 is ideal for constructing asphalt pavements in regions with varying temperatures, providing a reliable and flexible surface.
Repair and Maintenance: VG 20’s superior binding characteristics make it suitable for repairing and patching existing bituminous pavements, helping to extend their lifespan and enhance their durability.

Technical Specifications

VG 20 bitumen meets stringent technical standards, ensuring high performance and reliability. Key specifications include:

Penetration Value: VG 20 has a penetration value between 40-60, indicating a slightly firmer consistency compared to VG 10 but still suitable for a variety of applications.
Viscosity: At 60°C, VG 20 bitumen has a viscosity of 1500-3000 poise, making it well-suited for moderate climates and various construction needs.
Softening Point: The softening point of VG 20 is generally around 50-60°C, ensuring stability and effectiveness in a range of temperatures.
Ductility: VG 20 exhibits good ductility, allowing it to withstand traffic loads and temperature fluctuations without breaking.
