Bitumen VG-30 is one of the most widely used Viscosity Grade bitumens, primarily applied in road construction projects in hot and moderate climates. It is specifically designed for asphalt pavements subjected to heavy traffic loads. Compared to softer grades like VG-10 and VG-20, VG-30 has a higher viscosity and provides greater resistance to rutting and deformation under high temperatures. This grade is highly durable, offering excellent adhesion, weather resistance, and long service life.

These parameters ensure VG-30 is a high-performance binder capable of handling high traffic and hot weather conditions.
• High resistance to rutting: Prevents permanent deformation in heavy-traffic pavements.
• Excellent adhesion: Provides strong bonding with aggregates for long-lasting roads.
• Durability in hot climates: Performs well under sustained high pavement temperatures.
• Oxidation and weather resistance: Maintains stability under environmental stresses.
• Improved load-bearing capacity: Ideal for national highways and expressways.
• National highways and expressways with heavy axle loads.
• Airport runways and taxiways requiring strong resistance to deformation.
• Urban and arterial roads with high traffic density.
• Asphalt concrete mixes for medium to high traffic conditions.
• Industrial pavements and ports exposed to heavy loads.
Bitumen VG-30 is available in:
• New steel drums (200 kg net)
• Jumbo bags (1 MT)
• Bulk shipments for large-scale infrastructure projects
• Store in dry, ventilated warehouses, away from direct heat or moisture.
• Avoid heating above 175–180°C to prevent product degradation.
• Use protective clothing, gloves, and goggles when handling hot bitumen.
• Follow international safety and transportation regulations.
