    Frequently Asked Questions.

    Our 70/100 penetration grade bitumen is a soft paving binder offering enhanced flexibility and crack resistance for moderate to cooler climate conditions.

    Bitumen 70/100 is a penetration grade paving bitumen with a penetration value of 70 to 100 (0.1mm at 25°C), making it a soft, flexible binder suited for asphalt and road construction.

    Bitumen 70/100 has a penetration range of 70–100 decimillimetres, tested at 25°C under 100g load for 5 seconds per EN 1426, with a softening point of 43–53°C.

    Bitumen 70/100 is softer and more flexible than Bitumen 50/70, offering better resistance to low-temperature cracking, while Bitumen 50/70 suits warmer, higher-traffic applications.

    Black Rock Bitumen supplies Bitumen 70/100 to the EN 1426 penetration grade standard; equivalent ASTM grades like Bitumen 80/100 are available separately for markets requiring ASTM specification.

    Bitumen 70/100 offers improved flexibility, strong low-temperature crack resistance, easy workability, and reliable performance across moderate and cooler climate paving projects.

    Bitumen 70/100 should be stored in heated tanks within recommended temperature limits, protected from overheating, and handled with clean equipment to maintain quality and specification compliance.

    Black Rock Bitumen supplies Bitumen 70/100 in jumbo bags, steel drums, and bulk containers (Bitutainers/Bituboxes), allowing flexible shipment sizes for contractors and EPC companies.

    Bitumen 70/100 is used in road construction, urban and rural paving, asphalt concrete mixes, and low-to-medium traffic pavements, especially across temperate and cooler climate regions.
