Bitumen 70/100 is a widely used penetration grade bitumen designed for paving and construction works in moderate to cold climates. Produced by the distillation of carefully selected crude oils, this grade is classified as a softer binder compared to 35/50, 40/50, or 60/70, which makes it highly suitable for regions where temperature fluctuations and flexibility requirements are critical. Its penetration value indicates that it provides excellent workability, strong adhesion, and durability under standard traffic conditions.

These technical characteristics make Bitumen 70/100 an adaptable and reliable binder for paving applications in areas exposed to low temperatures and moderate traffic loads.
• High flexibility: Prevents cracking under cold weather conditions.
• Strong adhesion to aggregates: Ensures durability in asphalt mixtures.
• Moderate stiffness: Balances resistance to rutting with flexibility.
• Weathering resistance: Performs well under oxidation and long-term exposure.
• Workability: Easier handling during mixing and compaction processes.
• Road construction: Suitable for urban and rural roads with medium traffic.
• Cold and moderate climate pavements: Prevents brittleness and cracking under temperature variations.
• Airport taxiways and parking areas: Performs reliably under medium loads.
• Asphalt concrete production: Commonly used in hot mix asphalt (HMA) for standard paving applications.
• Infrastructure projects in colder regions: Offers long-term stability and flexibility.
Bitumen 70/100 is usually available in:
• New steel drums (200 kg net)
• Jumbo bags (1 MT)
• Bulk shipments for industrial-scale applications
• Store in cool, dry, and ventilated storage areas, away from open flames.
• Wear appropriate protective equipment during handling.
• Avoid overheating; maximum safe heating temperature is 200°C.
• Follow international safety and occupational guidelines during transportation and use
