Bitumen VG-40 is the hardest grade of viscosity grade bitumens, specifically engineered for high-stress road construction projects such as expressways, heavy-duty highways, and industrial pavements. With its very high viscosity and stiffness, VG-40 provides maximum resistance to rutting, deformation, and heavy axle loads, making it the preferred choice for areas exposed to extreme traffic intensity and high pavement temperatures.

These parameters highlight the high stiffness and superior load-bearing capacity of VG-40, making it the most suitable binder for extreme traffic and climatic conditions.
• Maximum rutting resistance: Prevents deformation under heavy and repeated axle loads.
• Superior durability: Ensures long service life in high-temperature regions.
• Excellent adhesion to aggregates: Provides stability and strength to asphalt layers.
• Resistance to oxidation and weathering: Maintains long-term performance under harsh environments.
• High stiffness: Increases load distribution capacity for critical infrastructure.
• Expressways and national highways with very heavy traffic intensity.
• Airport runways and taxiways requiring maximum resistance to rutting.
• Industrial pavements, ports, and container yards exposed to continuous heavy loading.
• Urban arterial roads with high traffic density and stress.
• Hot mix asphalt (HMA) for demanding conditions in hot climates.
