What is Bitumen 30/45?

 Bitumen 30/45 is a penetration grade paving bitumen defined by a penetration value of 30–45 (0.1mm at 25°C) under ASTM D5. This penetration range makes Bitumen 30/45 harder than standard grades like 40/60, giving it exceptional resistance to deformation under sustained heavy traffic loads.

Black Rock Bitumen 30/45 carries a softening point of 52–60°C (ASTM D36) and ductility above 100cm (ASTM D113), ensuring flexibility without cracking. These properties make Bitumen 30/45 especially reliable for highways, expressways, and industrial roads operating in hot, high-temperature climate conditions.

Compared to softer grades, Bitumen 30/45 offers greater rutting resistance and long-term structural stability under heavy axle loads. Supplied in jumbo bags, drums, and bulk bitutainers, Bitumen 30/45 is certified to ASTM standards, making it a dependable binder choice for infrastructure and EPC contractors.

    Frequently Asked Questions.

    Our 30/45 penetration grade bitumen is a hard paving binder engineered for high-temperature and heavy-traffic asphalt applications.

    Bitumen 30/45 is a penetration grade paving bitumen with a penetration value between 30 and 45 (0.1mm at 25°C), indicating a hard, high-stability binder used in demanding paving applications.

    Bitumen 30/45 is harder and more resistant to rutting than Bitumen 40/60, making Bitumen 30/45 the preferred choice for heavier axle loads and higher pavement temperatures.

    Bitumen 30/45 offers excellent resistance to deformation, high durability under traffic stress, stable performance in hot climates, and a proven track record in heavy-duty paving projects.

    Bitumen 30/45 should be stored in heated tanks at controlled temperatures, protected from overheating, and kept free from moisture and contamination to preserve binder performance.

    Bitumen 30/45 is tested and supplied to ASTM (D5, D36, D113, D92) and EN 12591 penetration grade standards, ensuring consistent quality for infrastructure and EPC projects globally.

    Bitumen 30/45 is supplied in jumbo bags, steel drums, and bulk bitutainers or bituboxes, giving contractors flexible options based on project volume and shipping method.

    You can request a Bitumen 30/45 price quote by contacting Black Rock Bitumen directly with your required quantity, destination port, and packaging preference for a fast, tailored quotation.

    Bitumen 30/45 is commonly used in highways and expressways, heavy-traffic pavements, industrial roads, and warm-to-hot climate regions where deformation resistance is critical.
