Performance Grade (PG) Bitumen PG 70-10 is a high-quality asphalt binder designed to perform reliably in hot climates with very low winter temperatures. According to the Superpave performance grading system, this bitumen grade is engineered to resist rutting at high service temperatures (up to 70°C) while maintaining flexibility and crack resistance at low temperatures (-10°C). Its balanced rheological properties make PG 70-10 ideal for high-traffic roads, highways, and airport pavements where both durability and resistance to temperature extremes are required.

These specifications ensure superior rutting resistance in hot weather while preventing thermal cracking during cold seasons.
• High rutting resistance: Withstands permanent deformation under heavy traffic at elevated temperatures.
• Thermal cracking resistance: Maintains flexibility and strength in cold temperatures down to -10°C.
• Improved adhesion: Ensures strong bonding with aggregates, enhancing pavement durability.
• Oxidation resistance: Maintains stability under long-term aging and environmental exposure.
• Enhanced durability: Suitable for long-life pavement design under harsh weather and traffic conditions.
• Highways and expressways in hot climates with cold winters.
• Airport runways and taxiways requiring high performance under load and temperature stress.
• Urban and regional roads with heavy traffic exposure.
• Industrial pavements and container terminals subjected to dynamic loads.
• Asphalt mixes designed using Superpave specifications.
