Bitumen 60/70 is one of the most commonly used penetration grade bitumen types in the global market. Produced through the fractional distillation of crude oil, this grade is classified as a medium penetration binder, softer than grades such as 35/50 and 40/50, but harder than 80/100. It provides an excellent balance between flexibility, adhesion, and durability, making it ideal for a wide variety of asphalt and road construction projects.

This penetration range ensures that Bitumen 60/70 is a standard paving grade, suitable for both moderate and tropical climates.
• Excellent flexibility: Prevents cracking under moderate temperature variations.
• Strong adhesion: Binds aggregates effectively in asphalt mixtures.
• Durability: Resistant to rutting, deformation, and weathering.
• Thermoplastic performance: Softens upon heating, hardens when cooled, and maintains consistency.
• Workability: Easier handling and mixing compared to harder grades.
• Road construction: Widely used in highways, streets, and rural roads.
• Airport pavements: Performs reliably under standard aircraft loads in moderate climates.
• Asphalt production: Common binder for hot mix asphalt (HMA) and asphalt concrete.
• Industrial flooring and pavements: Suitable for surfaces exposed to medium vehicle traffic.
• Infrastructure in warm and moderate climates: Prevents excessive softening while ensuring flexibility.
Bitumen 60/70 is generally supplied in:
• New steel drums (200 kg net)
• Jumbo bags (1 MT)
• Bulk shipments for large-scale projects
• Store in dry, ventilated warehouses away from direct heat and ignition sources.
• Use protective clothing and equipment to prevent burns or inhalation.
• Avoid heating above 200°C to prevent degradation.
• Follow global occupational health and safety standards during transport and handling
