Bitumen 80/100 – Penetration Grade Bitumen for Road Construction & Highways

 Bitumen 80/100 is a widely used penetration-grade bitumen with a penetration value of 80–100 dmm, offering reliable and durable performance for road construction, highways, and heavy-duty paving. Engineered to withstand traffic loads and varying weather conditions, Bitumen 80/100 ensures long-lasting strength and superior adhesion for quality infrastructure projects.

What Is Bitumen 80/100?

Bitumen 80/100 is a popular penetration grade bitumen with a penetration value ranging from 80 to 100 at 25°C. Softer than 60/70 grade, Bitumen 80/100 offers enhanced flexibility and workability, making it well-suited for moderate climate road construction and general paving applications requiring good ductility.

Bitumen 80/100 is commonly used in highway construction, rural road paving, and asphalt mix production in temperate climate zones. Its softer consistency improves workability at lower temperatures and reduces cracking risk. Bitumen 80/100 also performs well in surface dressing, tack coats, and waterproofing membrane applications.

Blackrock Bitumen supplies high-quality Bitumen 80/100 manufactured to meet international penetration, softening point, and ductility standards. Our Bitumen 80/100 undergoes strict quality testing to ensure consistent performance for contractors and infrastructure projects worldwide.

What is bitumen 80/100?

Bitumen 80/100 is a penetration grade bitumen with a needle penetration value between 80 and 100 (measured in units of 0.1 mm) at 25°C under a 100g load for 5 seconds per ASTM D5. The penetration value directly indicates the consistency and hardness of the bitumen — a higher number means a softer, more pliable material. As a result, Bitumen 80/100 sits at the softer end of the paving grade spectrum, making it especially well-suited for road construction in moderate to cool climates where flexibility and crack resistance are priorities.

Classified under ASTM D946 and AASHTO M20, this grade is produced through the vacuum distillation of crude oil. The resulting material is a dark brown-to-black, semi-solid thermoplastic substance that softens when heated and hardens when cooled. Its thermoplastic behaviour makes it highly workable during application and reliably stable once in service.

Black Rock Bitumen supplies Penetration Grade Bitumen 80/100 sourced from quality-controlled refineries, inspected by independent third parties, and shipped in new steel drums, jumbo bags, or bulk containers to destinations across Africa, Asia, the Middle East, and the GCC.

Key properties & technical characteristics

Bitumen 80/100 delivers a precise balance of softness, adhesion, and durability. Its softening point of 42–50°C (per ASTM D36) means it begins to flow at moderate temperatures, which is ideal for blending into hot-mix asphalt (HMA) and achieving uniform coating of aggregates. Its ductility value of 100 cm minimum (ASTM D113) reflects exceptional elasticity — the material can stretch significantly before failing, which resists cracking under thermal cycling and traffic stress.

With a flash point above 250°C (ASTM D92), it is safe for high-temperature mixing operations. Solubility in trichloroethylene of 99% minimum confirms a high degree of purity and minimal inert content. These properties together make 80/100 one of the most reliable paving grade bitumens for projects demanding long-term pavement performance.

Due to its higher viscosity compared to softer grades, bitumen 80/100 enables a thinner pavement design — industry data indicates up to a 30% reduction in asphalt volume applied without compromising structural performance.

Applications & use cases

The primary application of Bitumen 80/100 is in the production of hot mix asphalt (HMA) for base courses and wearing courses. Its combination of flexibility, adhesion, and load-bearing performance makes it effective across a wide range of infrastructure applications:

Road Construction

Base and wearing course binder for highways, national roads, and urban streets in moderate-to-cool climates.

Flexible Pavement

Used in flexible pavement design where traffic-induced deflection must be absorbed without surface cracking.

Waterproofing

Applied in roofing systems, foundation waterproofing, & drainage structures owing to its impermeable surface film.

Airport Runways

Suitable for light-load aprons and taxiways in cooler environments requiring fatigue resistance.

Bitumen Emulsion Base

Commonly used as a feedstock for manufacturing cationic and anionic bitumen emulsions.

Industrial Coatings

Applied as a protective bituminous coating on pipelines, steel structures, and underground installations.

    Frequently Asked Questions.

    Grade 80/100 Penetration Bitumen provides durable, high-quality performance for roads and heavy-duty paving.

    Penetration Grade Bitumen 80/100 is a semi-soft paving bitumen, measured by the depth a standard needle penetrates under specific conditions. It's widely used in road construction and waterproofing.

    It is mainly used for flexible pavements, asphalt mixes, and road surfacing where medium hardness and good binding properties are required.

    It offers a balance of hardness and flexibility, ensuring durability, resistance to deformation under traffic, and effective adhesion with aggregates.

    Store in a clean, dry area away from moisture and direct sunlight. Maintain proper temperature to avoid hardening or softening before use.

    We supply high-quality, reliable bitumen with consistent penetration values, ensuring optimal performance in road construction and infrastructure projects.

    Bitumen 80/100 is softer (penetration 80–100 vs 60–70) and has a lower softening point (42–50°C vs 48–56°C), making it better suited to moderate-to-cool climates where flexibility and crack resistance matter most. Bitumen 60/70 is stiffer and better suited to hotter climates where rutting resistance is the priority.

    Yes. Bitumen 80/100 is commonly used as a feedstock for manufacturing both cationic and anionic bitumen emulsions due to its workable consistency and good aggregate adhesion.

    Under ASTM D113, Bitumen 80/100 must achieve a minimum ductility of 100 cm at 25°C, reflecting its high elasticity and resistance to cracking under thermal cycling.
