Chinese Standard Bitumen
等级 – AH50
Petra Oil’s AH-50 is a high-quality penetration grade bitumen designed to deliver durable, long-lasting performance for a wide range of paving and infrastructure applications. Classified under penetration grade asphalt, AH-50 is well-suited for regions with moderate to high temperatures and where flexible pavement performance is essential.
With a penetration value of approximately 50 (measured in 0.1 mm units at 25°C), AH-50 offers a balanced blend of hardness and flexibility. It is less susceptible to deformation under heavy traffic loads while still maintaining sufficient elasticity to resist cracking under thermal stress. This makes it a preferred choice for roadways, highways, airport runways, and other infrastructure projects where high load resistance and extended pavement life are required.
Produced in adherence to ASTM D946 or AASHTO M20 standards, AH-50 guarantees consistent quality, optimum viscosity, and high-temperature performance. It adheres well to aggregates and offers excellent mixing and compaction properties, enhancing pavement strength and cohesion.
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.
等级 – AH90
AH90 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.
