Bitumen 200/300 – Soft Penetration Grade Bitumen for Low-Temperature Environments

Bitumen 200/300 is a soft penetration-grade bitumen with a penetration value of 200–300 dmm, offering superior softness and binding efficiency for low-temperature environments. This penetration grade bitumen is ideal for flexible pavements requiring enhanced workability, making Bitumen 200/300 a  long-lasting solution for cold-climate paving applications.

What is Bitumen 200/300?

Bitumen 200/300 is a very soft penetration grade bitumen with a penetration value ranging from 200 to 300 at 25°C. Among the softest grades available, Bitumen 200/300 offers exceptional flexibility and workability, making it ideal for extreme cold climate applications and specialized industrial uses requiring high ductility.

Bitumen 200/300 is primarily used in very cold regions for road construction, where soft binders prevent brittle cracking at low temperatures. This grade also serves in modified bitumen production, industrial applications, and paint manufacturing. Bitumen 200/300 suits priming coats and applications demanding maximum flexibility and adhesion.

Blackrock Bitumen supplies premium Bitumen 200/300 manufactured to meet international penetration, softening point, and ductility standards. Our Bitumen 200/300 undergoes rigorous quality testing to ensure consistent performance for contractors and industrial clients worldwide. Choose Blackrock Bitumen for reliable, high-quality, and specification-compliant Bitumen 200/300 supply.

Advantages of Bitumen 85/35

Softening point of 85–95°C provides excellent heat stability on flat and low-pitch roofs in tropical and arid climates
Penetration of 30–40 dmm delivers balanced flexibility resists cold cracking without compromising heat resistance
Excellent compatibility with APP (atactic polypropylene) modifiers for polymer-modified membrane production
Strong self-adhesion and bonding to concrete, steel, and mineral substrates when torch-applied at correct temperature

Advantages of Bitumen 200/300

EN 12591 (European Standard) classifies penetration grade bitumen by its penetration value and softening point range. Black Rock Bitumen supplies all major EN grades, tested and certified for export from our Dubai logistics hub.

Bitumen 20/30

Hard binder with low penetration & high softening point. Used in high-stress pavements, industrial roads, and airport runways in hot climates. Provides rut resistance under extreme thermal and mechanical stress.

Bitumen 30/45

Firm, high-softening-point binder with a penetration of 30–45 (0.1mm at 25°C). Ideal for highways, expressways, and heavily trafficked urban roads in hot climates. Delivers consistent deformation resistance under sustained axle loads.

Bitumen 35/50

A firm, durable grade widely used in base course and binder course layers across GCC, African, South American and South Asian road infrastructure projects. Performs reliably under moderate-to-heavy traffic volumes and varying climate conditions.

Bitumen 40/60

Semi-hard grade with balanced softening point, suited for urban road construction where surface temperatures exceed 50°C. Delivers strong adhesion to aggregate and resists permanent deformation.

Bitumen 50/70

One of the most commonly specified grades globally. Suitable for wearing course and binder course in temperate to hot climates. Widely used in road construction across the UAE, East Africa, and Southeast Asia.

Bitumen 70/100

A medium-grade binder offering a balance between stiffness and flexibility. Preferred for roads with moderate traffic and climate variability — including transitional regions in Central Asia and parts of Africa.

    Frequently Asked Questions.

    Penetration Grade 200/300 bitumen offers high softness and excellent binding properties, ideal for low-temperature applications and flexible pavements.

    It is a soft bitumen with high penetration value, mainly used for flexible pavements and low-traffic roads.

    Ideal for rural roads, temporary pavements, roofing, and other low-stress construction applications.

    High softness, excellent workability, and good adhesion, making it suitable for hot climates and low-load areas.

    It is typically heated and applied as a binder in road surfacing, sealing, or mixed with aggregates for flexible pavements.

    We ensure consistent quality, global standards compliance, and reliable supply for all infrastructure and paving projects.

    Bitumen 200/300 has a softening point of 52–60°C per ASTM D36. Note: this is notably higher than the softer, lower-penetration grades in the range — worth double-checking with your lab data, since it doesn't follow the usual pattern where higher penetration correlates with lower softening point (as seen across 60/70 through 120/150).

    Bitumen 200/300 has a much wider and higher penetration range (200–300 vs 120–150), making it the softest standard penetration grade Black Rock Bitumen supplies. It's typically reserved for cold-climate paving, low-traffic rural roads, and specialty sealing work rather than mainstream highway construction.

    Bitumen 200/300 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.
