Bitumen, also known as asphalt cement, is a viscous, black, semi-solid hydrocarbon material obtained as the heaviest fraction remaining after atmospheric and vacuum distillation of crude oil. Chemically, it is a complex blend of aromatics, resins, saturates, and asphaltenes, and it stands among the most strategic derivatives of the oil and petrochemical industry, playing a foundational role in road construction, waterproofing, and industrial insulation worldwide.
Holding one of the world’s largest proven crude oil reserves and operating a network of advanced refineries, Iran ranks among the leading bitumen producers and exporters in the Middle East. The high asphaltene content and favorable thermal stability of Iranian heavy crude provide an excellent base for producing bitumen grades that meet consistent demand across South Asian, African, and Persian Gulf markets.
