Viscosity Bitumen (VG Grade) – High-Quality Export Grade — Export from Iran
Viscosity Bitumen, also known as VG Bitumen (Viscosity Grade), is classified based on its absolute viscosity at 60°C. This grading system ensures consistent performance under high-temperature and heavy-traffic conditions, making it ideal for modern road construction in hot climates.
We supply high-quality Viscosity Bitumen from major Iranian refineries, produced under strict quality control and in compliance with IS 73:2013 and ASTM D3381 standards. Ideal for bulk export to infrastructure markets in Africa, Asia, and the Middle East.
Note: VG grading is based on viscosity (in Poise) at 60°C. Higher VG = higher viscosity = better performance in hot weather and under heavy loads.
🛣️ Janis Group VG Bitumen Capability: We supply premium Viscosity Grade (VG) Bitumen directly from major Iranian refineries, offering precise grading (VG10 to VG40) tailored to specific climatic and traffic conditions. Every shipment undergoes rigorous viscosity, penetration, and ductility testing via SGS inspection, ensuring maximum rutting resistance and durability for global highway and infrastructure projects.

Applications
- Highway Construction: Primary binder for roads in hot and moderate climates
- Heavy-Duty Pavements: Ports, airports, and industrial zones subjected to extreme loads
- Overlay & Rehabilitation: Strengthening existing road networks
- Bituminous Concrete (HMA): Enhanced durability and resistance to deformation
- Prime Coats: VG10 is specifically used for sealing granular bases
Which VG Grade Fits Your Project Conditions?
VG10 (Moderate / Cold Climates)
Key Strength: Lower viscosity for excellent flow and thermal cracking resistance.
Choose this if: Your project is in a moderate/cold region or requires a prime coat for granular bases.
Typical buyers: Road authorities in temperate zones, emulsion manufacturers.
VG30 (Hot Climates / Heavy Traffic)
Key Strength: Optimal balance of rutting resistance and workability.
Choose this if: You are building major highways in hot climates where standard binders would deform under traffic.
Typical buyers: National highway departments, Middle East/Africa infrastructure projects.
VG40 (Extreme Heat / Ultra Heavy Duty)
Key Strength: Maximum viscosity for superior resistance to permanent deformation.
Choose this if: Your project involves ports, airports, or industrial zones with extremely heavy, slow-moving loads.
Typical buyers: Port authorities, heavy industrial zone developers, specialized contractors.
Key Notes
- Viscosity Grade: Based on performance at 60°C. Higher VG = better resistance to rutting and deformation.
- Penetration: Decreases as VG increases — harder bitumen for hot regions.
- Ductility: Sufficient for flexibility under traffic load, preventing premature cracking.
- All values comply with IS 73:2013 and can be adjusted to meet EN or Gulf standards.
- Pre-shipment inspection by SGS is included for every shipment.
Frequently Asked Questions (FAQ)
VG classifies bitumen by absolute viscosity at 60°C, providing a more accurate prediction of rutting resistance under heavy traffic and high heat compared to Penetration Grade, which only measures hardness at 25°C.
VG30 is the most widely used grade for hot climates and heavy traffic. For extreme heat or very heavy loads (like ports), VG40 is recommended.
Minimum order is 200 MT per shipment, supplied in bulk heated tankers, flexi-bags (18–22 MT per 20ft container), jumbo bags, or steel drums.
Yes. While our standard production complies with IS 73:2013 and ASTM D3381, we can adjust the refining process to meet specific EN or Gulf standards upon request.
VG10 has lower viscosity, making it ideal for moderate/cold climates where thermal cracking is a bigger risk than rutting. It is also commonly used for prime coats due to its excellent flow characteristics.
