Bitumen 80/100 is a soft penetration grade bitumen primarily used in paving projects located in cold and moderate climates. It is obtained from the distillation of carefully selected crude oils and classified as one of the softer penetration grades, making it highly suitable for regions where flexibility and resistance to thermal cracking are essential. With a relatively high penetration range, Bitumen 80/100 provides excellent workability, adhesion, and durability under medium traffic conditions.

These specifications make Bitumen 80/100 an ideal choice for cold regions where the pavement must withstand contraction and expansion cycles without cracking.
• High flexibility in cold climates: Reduces the risk of surface cracking during freeze-thaw cycles.
• Excellent adhesion: Ensures a strong bond with aggregates for durable asphalt mixes.
• Good workability: Easy to handle and mix compared to harder grades.
• Weather resistance: Performs reliably under oxidation and long-term environmental exposure.
• Medium stiffness: Provides balance between rutting resistance and flexibility.
• Road construction in cold climates: Suitable for urban, rural, and regional roads.
• Asphalt concrete production: Common binder for hot mix asphalt (HMA) in colder environments.
• Airport pavements and taxiways: Performs under medium load conditions.
• Industrial pavements and parking lots: Reliable for areas with moderate vehicle traffic.
• Infrastructure exposed to temperature fluctuations: Prevents premature cracking.
Bitumen 80/100 is generally supplied 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 heat and ignition sources.
• Use appropriate protective equipment during handling to avoid burns.
• Do not exceed 200°C during heating to avoid degradation.
• Follow international safety and occupational health standards for storage and transport
