Bitumen 10/20 – Hard Grade Penetration Bitumen for Heavy-Duty Paving

Bitumen 10/20 is a hard-grade penetration bitumen with a penetration value of 10–20 dmm, engineered for exceptional stiffness and long-lasting durability under heavy-duty traffic loads. This high-hardness bitumen resists deformation and rutting even at elevated temperatures, making Bitumen 10/20 the preferred choice for high-stress pavements, airport runways, and industrial-grade road construction.

What Is Bitumen 10/20?

 Bitumen 10/20 is a hard penetration grade bitumen known for its high stiffness and low penetration value between 10 and 20 at 25°C. Unlike softer grades, Bitumen 10/20 offers exceptional resistance to deformation, making it suitable for high-temperature climates and heavy-load industrial applications.

Bitumen 10/20 is widely used in polymer modified bitumen production, industrial coatings, and specialty applications requiring high hardness. This grade also serves as a base for manufacturing oxidized bitumen and roofing-grade products. Bitumen 10/20 performs reliably in applications demanding rigidity, low thermal susceptibility, and structural stability.

Blackrock Bitumen supplies premium Bitumen 10/20 manufactured under strict quality control to meet international hardness and penetration standards. Our Bitumen 10/20 undergoes thorough testing for consistency, purity, and performance, supporting manufacturers and industrial clients worldwide. Choose Blackrock Bitumen for trusted, high-grade, and specification-compliant bitumen supply.

    Frequently Asked Questions.

    Penetration Grade Bitumen 10/20 is a hard-grade bitumen offering high stiffness, durability, and resistance to deformation under heavy loads.

    Penetration Grade Bitumen 10/20 is a very hard paving-grade bitumen with low penetration value, ideal for high-load applications.

    It is widely used in heavy-duty road construction, airport runways, industrial pavements, and high-temperature regions.

    This grade offers excellent resistance to deformation, high stability under heavy traffic, and superior performance in hot climates.

    Yes, its hard consistency makes it highly suitable for high-temperature environments where softer grades may deform.

    Yes, Black Rock Bitumen supplies Grade 10/20 in bulk, drums, and jumbo bags, meeting international ASTM and EN standards.

    Bitumen 10/20 has a softening point of 58–66°C per ASTM D36 — significantly higher than standard paving grades like 60/70 or 80/100, reflecting its very hard, low-penetration nature.

    Bitumen 10/20 has a penetration of only 10–20 (0.1mm) versus 60–70 for standard paving bitumen, making it far harder and stiffer. It's typically used as a feedstock for oxidized/blown bitumen production and specialty industrial applications rather than direct road paving.

    Bitumen 10/20 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.
