What Is Bitumen 160/220?

 Bitumen 160/220 is a soft penetration grade bitumen commonly used in road construction and industrial applications. With a penetration value ranging from 160 to 220 at 25°C, this grade offers superior flexibility and workability, making Bitumen 160/220 ideal for cold climate paving and specialized asphalt formulations.

Bitumen 160/220 is primarily used in colder regions where softer binders prevent cracking under low temperatures. This grade suits modified bitumen production, industrial applications, and paint manufacturing. Bitumen 160/220 also performs well in surface dressing, priming coats, and low-traffic road construction requiring enhanced ductility and adhesion.

Blackrock Bitumen delivers high-quality Bitumen 160/220 manufactured to meet international penetration, ductility, and softening point standards. Our Bitumen 160/220 is rigorously tested for consistency and performance, serving contractors, manufacturers, and infrastructure projects globally. Partner with Blackrock Bitumen for  quality-assured products.

    Frequently Asked Questions.

    Our 160/220 penetration grade bitumen is a soft paving binder designed for flexibility and crack resistance in cold and temperate climates.

    160/220 bitumen is a penetration grade paving bitumen with a penetration value between 160 and 220 (0.1mm at 25°C), indicating a soft, highly flexible binder.

    160/220 is softer and more flexible, with a much wider penetration range, offering better resistance to cracking in low-temperature conditions than the harder 60/70 grade.

    It offers excellent flexibility, improved low-temperature cracking resistance, easy workability, and suitability for cooler climates.

    Store in heated tanks at controlled temperatures, avoid overheating, and maintain clean handling practices to preserve binder quality.

    Bitumen 160/220 has a softening point of 35–43°C per ASTM D36 — one of the lowest ranges in Black Rock Bitumen's penetration grade lineup, reflecting its very soft, cold-climate-optimized consistency.

    Bitumen 160/220 is tested to ASTM standards, including ASTM D5 (penetration), ASTM D36 (softening point), ASTM D113 (ductility), ASTM D92 (flash point, min. 230°C), and ASTM D2042 (solubility in trichloroethylene, min. 99%).

    Under ASTM D113, Bitumen 160/220 must achieve a minimum ductility of 100 cm at 25°C, confirming its very high elasticity for cold and variable-climate applications.

    It is widely used in road construction in cold and temperate climates, surface dressing, low-to-medium traffic pavements, and asphalt mixes requiring flexibility.
