🏭 Industrial Applications of Oxidized Bitumen Grades

Each grade is formulated to match specific thermal resistance, mechanical durability, and chemical stability needs:

🧱 Structural Joint Sealing

Grades like 85/40, 90/40, and 105/35 are ideal for rigid expansion joints in bridges, highways, and industrial flooring where flexibility is minimal and stability under pressure is critical.

🛢️ Steel Pipe and Tank Coating

Grades like 90/15, 95/25, and 110/30 offer outstanding corrosion resistance and waterproofing when applied to steel pipelines, storage tanks, and marine systems.

🧪 Chemical Containment Systems

With low ductility and high flash points, grades such as 90/10 and 105/15 are used in basins, containment areas, and reactors in chemical processing plants.

🏠 Roofing and Insulation Systems

Grades like 75/25, 85/30, and 115/15 serve in multilayer roofing systems to act as durable waterproof membranes resistant to UV and heat.

🧰 Rigid Adhesives and Industrial Mastics

Used in cold-applied and hot-applied adhesive systems, grades like 75/30, 85/30, and 90/40 deliver long-lasting performance in glues, mastics, and filler products.

FAQs about Oxidized Bitumen Grades

What is the main difference between oxidized and penetration bitumen?

Penetration bitumen is softer and temperature-sensitive, while blown asphalt has been air-blown to enhance hardness, aging resistance, and thermal stability.

How is oxidized bitumen applied in waterproofing?

It is melted and applied as a liquid sealant in layers. Upon cooling, it hardens into a waterproof, chemically-resistant layer for foundations, tunnels, and rooftops.

Which grade is best for expansion joints?

Grades such as 90/40, 105/35, and 110/30 are best due to their hardness, low ductility, and resistance to temperature fluctuations.

Is oxidized bitumen environmentally safe?

Yes, when used properly. It is inert, non-volatile, and has minimal leaching, making it suitable for sealed applications in construction and industry.

Can oxidized bitumen be blended with solvents or polymers?

Yes, with ≥99% solubility in TCE, it is compatible with a wide range of solvents, and can also be modified with SBS/APP polymers for enhanced flexibility.
