What Is Bitumen C240?

Bitumen C240 is a viscosity-graded bitumen manufactured to Australian Standard AS 2008 specifications, with a viscosity of approximately 240 Pa·s at 60°C. Harder than C170 grade, Bitumen C240 offers increased stiffness and resistance to deformation, making it suitable for higher-temperature and heavier-traffic road applications.

Bitumen C240 is commonly used in sprayed sealing, asphalt production, and road surfacing in warmer Australian regions requiring greater rutting resistance. Its firmer consistency improves durability under heavy traffic loads and elevated temperatures. Bitumen C240 also suits primer sealing and stabilization work demanding enhanced structural stability.

Blackrock Bitumen supplies high-quality Bitumen C240 manufactured to meet Australian Standard AS 2008 viscosity and quality requirements. Our Bitumen C240 undergoes strict quality testing to ensure consistent performance for contractors and infrastructure projects across Australia. Choose Blackrock Bitumen for reliable, compliant, and specification-grade Bitumen C240 supply.

Applications of Bitumen C240?

Dense-graded asphalt concrete

Dense-graded asphalt concrete (DGAC) wearing and binder courses on state highways, urban arterials, and collector roads in temperate eastern Australian climates

Open-graded asphalt

Open-graded asphalt (OGA) and stone mastic asphalt (SMA) surface courses on standard traffic roads, where C240 provides the right balance of drainage and structural performance

Sprayed sealing

Sprayed sealing on primary and secondary sealed roads in temperate regions where C170 is considered too soft and C320 too stiff for the prevailing conditions

Urban road

Urban road construction and rehabilitation in major cities including Sydney, Melbourne, Adelaide, and Perth, where moderate temperatures and heavy urban traffic coexist

Advantages of Bitumen C240 Bitumen

    Frequently Asked Questions.

    Australian Standard C240 bitumen is a hard paving grade with high viscosity and durability, ideal for heavy traffic roads and demanding infrastructure applications.

    C240 is a high-viscosity paving bitumen manufactured to Australian Standards, commonly used for heavy-duty road construction and asphalt production.

    Where is C240 bitumen commonly used?

    C240 is ideal for highways, major roads, airport pavements, and high-traffic asphalt applications requiring strong load-bearing performance.

    It offers excellent resistance to deformation, strong adhesion to aggregates, and durable performance under high temperatures and traffic loads.

    Yes. Black Rock Bitumen supplies C240 that meets Australian Standard specifications, ensuring consistent quality and reliable field performance.

    C240 is available in bulk, steel drums, and bitumen bags, with export-ready packaging suitable for domestic and international projects.

    Yes. C240 is the standard base binder for producing Austroads A10E and A20E polymer-modified bitumens (PMBs) and other modified grades. SBS, EVA, and crumb rubber modifiers are blended with C240 to produce high-performance binders for premium highway applications.

    Bitumen C240 has a softening point (Ring & Ball) of 39–47°C per AS 2008:1997, which is moderate — higher than C170 (more rutting resistance) but lower than C320 (more flexibility in cooler conditions).

    C240 is stiffer (200–300 Pa·s vs 100–200 Pa·s), has a higher softening point (39–47°C vs 36–43°C), and is more suitable for general highway paving. C170 is softer, better for sprayed sealing and cold-climate applications. Most temperate-climate main roads in Australia specify C240, not C170.

    Yes. Black Rock Bitumen exports AS 2008:1997-compliant C240 to Australian importers from Dubai in bulk heated tankers and 200 kg new steel drums. Full AS 2341 test certificates, COA, MSDS, and import clearance documentation are provided with every shipment.

    Under AS 2008:1997, C240 must have a mass loss of ≤ 0.5% after RTFOT (Rolling Thin Film Oven Test, AS 2341.22 / ASTM D2872) and a RTFOT residue viscosity ratio of ≤ 3.0, ensuring the binder does not excessively harden during hot-mix plant production.
