Engineered for Performance, Trusted Worldwide

Oxidized bitumen, also known as blown asphalt, is engineered to handle demanding environments. Whether it’s waterproofing high-rise buildings or coating pipelines, it delivers long-lasting performance where ordinary bitumen falls short. At Blackrock, we supply premium-grade oxidized bitumen tailored for industrial strength and global reliability. performance.

Why Choose Oxidized Bitumen?

Not all bitumen are built the same. Oxidized bitumen is specially processed with controlled air-blowing to improve its thermal stability and durability.

Stays solid in hot conditions and flexible in colder ones.

Resists aging, cracking, and chemical breakdown better than standard bitumen.

Essential for industries where performance, precision, and reliability are non-negotiable.

Why BlackRock Bitumen Stands Out

Local Expertise, Global Standards

While we comply with AS 2008, our refining processes also align with international best practices.

Climate-Adapted Formulations

Our bitumen resists UV degradation, rutting, and thermal cracking that adapts to any climatic conditions.

Sustainable Sourcing

We focus on low-emission production and ensure our products are fully recyclable, reducing waste and supporting sustainability.

Nationwide Supply Chain

We ensure reliable delivery, no matter if you're in Perth, Sydney, or a remote regional location, with timely and efficient service every time.

Applications Beyond Roads

While oxidized bitumen is the go-to solution for waterproofing, roofing, road construction, and industrial insulation worldwide, its uses extend to:

Pipe Coatings: Protects pipelines from corrosion and environmental damage, extending their service life.

Electrical Insulation: Used as an insulator in electrical products, offering high dielectric strength and thermal stability.

Automotive Coatings: Applied as underbody coatings in vehicles, providing protection against corrosion and mechanical damage.

Pavement & Road Surfacing: Enhances asphalt mixtures, improving resistance to deformation and extending pavement lifespan, especially in high-traffic areas.

Sealants & Joint Fillers: Used to fill gaps and joints in concrete structures, ensuring durability and flexibility under stress.

Technical Excellence – How We Ensure Quality

At Blackrock Bitumen, our oxidized bitumen is manufactured under strictly controlled conditions using state-of-the-art oxidation reactors to ensure consistent softening point, penetration, and durability across every batch.

Here’s how we ensure top-tier quality:

Controlled Production: We use modern oxidation reactors with tight control over temperature and airflow.

Lab -Tested Batches: Each batch is tested for softening point, penetration, ductility, and flash point before dispatch.

Smart Packaging: Products are packed in drums, bags, or blocks to protect quality in any climate.

Meets Global Standards: Our bitumen complies with ASTM, EN, and ISO specifications.

Expert Oversight: Engineers and QC experts monitor every step from start to finish.
