What is Bitumen 85/100?

Bitumen 85/100 is a penetration grade bitumen with a penetration value ranging from 85 to 100 at 25°C. Closely related to the 80/100 grade, Bitumen 85/100 offers a slightly narrower, tighter specification range, providing consistent flexibility and workability for moderate climate road construction and paving applications.

Bitumen 85/100 is commonly used in highway construction, rural road paving, and asphalt mix production where precise penetration control is required. Its softer consistency improves workability at lower temperatures and reduces cracking risk. Bitumen 85/100 also suits surface dressing, tack coats, and waterproofing membrane applications.

Blackrock Bitumen supplies high-quality Bitumen 85/100 manufactured to meet international penetration, softening point, and ductility standards. Our Bitumen 85/100 undergoes strict quality testing to ensure consistent performance for contractors and infrastructure projects worldwide.

    Frequently Asked Questions.

    Penetration Grade Bitumen 85/100 is a reliable and durable bitumen for flexible pavements, ensuring long-lasting road performance.

    Penetration Grade Bitumen 85/100 is a medium-soft bitumen commonly used in road construction and paving applications.

    It is ideal for flexible pavements, asphalt mixes, and waterproofing applications in moderate climates.

    Black Rock Bitumen ensures our 85/100 grade meets ASTM and EN standards for quality and performance.

    It maintains good stability under normal traffic conditions but may soften in extremely high temperatures.

    Our bitumen offers consistent quality, reliable performance, and global export-ready supply for construction projects.

    Bitumen 85/100 has a softening point of 46–56°C per ASTM D36, giving it a slightly wider working-temperature tolerance than 80/100.

    The two grades overlap significantly — 85/100 has a narrower minimum penetration (85 vs 80) but a notably higher softening point range (46–56°C vs 42–50°C). In practice, 85/100 is often specified where a project's regional standard calls for that exact grade name, while 80/100 is the more widely traded international default. Buyers should confirm which grade their project specification requires before ordering.

    Bitumen 85/100 is tested to ASTM standards, including ASTM D5 (penetration), ASTM D36 (softening point), ASTM D113 (ductility), ASTM D92 (flash point), and ASTM D2042 (solubility in trichloroethylene), with a minimum flash point of 250°C.
