Chinese Standard Bitumen
等级 – AH110
Petra Oil’s AH-110 is a soft-grade, high-penetration bitumen designed to deliver optimum flexibility and fatigue resistance in very cold climates or low-traffic road environments. With a penetration value around 110 dmm at 25°C, AH-110 is engineered to remain pliable and crack-resistant even under extreme temperature variations, making it suitable for roadways subjected to freeze-thaw cycles or where surface deformation risk is minimal.
AH-110 offers excellent low-temperature flow properties and can be mixed and compacted efficiently. Its viscoelastic characteristics provide superior resistance to thermal and fatigue cracking, particularly in northern regions or high-altitude zones. Manufactured in compliance with ASTM D946 and AASHTO M20 specifications, AH-110 is a dependable solution for applications that require enhanced flexibility and long-term durability.
等级 – AH50
AH50 Bitumen is high quality asphalt, derived from crude petroleum refining. AH70 Bitumen is dark in color and possesses waterproofing and adhesive properties. It is substantially non-volatile and softens gradually when heated.
等级 – AH70
AH70 Bitumen is high quality asphalt, derived from crude petroleum refining. AH70 Bitumen is dark in color and possesses waterproofing and adhesive properties. It is substantially non-volatile and softens gradually when heated.
