Bitumen 35/50 is a premium-grade paving bitumen, commonly used in road construction and industrial applications where high durability and resistance to heavy traffic loads are required. Classified under penetration grade bitumen, it is produced through the controlled distillation of crude oil, resulting in a hard, thermoplastic binder with exceptional performance characteristics.

These specifications make Bitumen 35/50 a hard-grade binder with reduced penetration values, suitable for regions with high ambient temperatures and for projects that demand a long-lasting pavement structure.
• High stiffness and durability: Ensure excellent resistance to rutting, deformation, and heavy loads.
• Thermoplastic behavior: Softens at elevated temperatures and hardens when cooled, providing strong adhesion to aggregates.
• Oxidation resistance: Designed for prolonged exposure to heat and weathering without significant performance loss.
• Versatility: Compatible with various aggregates and additives, enhancing performance in asphalt mixtures.
• Highway and expressway construction: Ideal for surfaces exposed to intense traffic and heavy axle loads.
• Airport runways: Withstands high tire pressures and extreme operational conditions.
• Industrial pavements: Suitable for areas requiring enhanced load-bearing capacity.
• Asphalt concrete and hot mix designs: Ensures stability and resistance against rutting and thermal cracking.
• Infrastructure in warm climates: Its low penetration grade prevents excessive softening under high temperatures.
Bitumen 35/50 is typically supplied in:
• New steel drums (200 kg net)
• Jumbo bags (1 MT)
• Bulk shipments for large-scale projects
• Store in a cool, dry environment away from direct sunlight.
• Avoid contact with skin and eyes during handling.
• Heating should be controlled to prevent thermal cracking or fire hazards (never exceed 200°C).
• Always follow standard occupational health and safety guidelines.
