Bitumen AH70 for highway pavements. Exported from Dubai.
A medium-hard penetration-grade binder made to GB/T 15180 for highway pavements.
Temperature-stable for highway pavements
Bitumen AH70 is a medium-hard penetration-grade bitumen from the Chinese AH series for heavy-traffic road asphalt, made to GB/T 15180. The grade name gives the nominal penetration (AH70 is about 70 dmm at 25°C).
It balances stiffness with enough flexibility to resist both rutting in heat and cracking in cooler weather, which suits highway base and wearing courses.
Black Rock Bitumen supplies Bitumen AH70 from Dubai to contractors, EPC companies and asphalt producers across Asia, Africa and the Middle East.
- Balanced hardness and flexibility
- Good resistance to rutting and cracking
- Suited to highway and arterial pavements
- Good adhesion to aggregate
- Consistent quality in every batch
