What Is Oxidized Bitumen 115/15?
Oxidized Bitumen 115/15, also known as Blown Asphalt 115/15, is a high softening point grade used in waterproofing, roofing, insulation, and industrial applications. Raha Oil is a reliable UAE-based supplier and exporter of Blown Asphalt 115/15, delivering consistent quality to customers across Africa, the GCC, and Asian markets at competitive prices with fast shipment.
Oxidized Bitumen 115/15 is a semi-solid petroleum product with a high softening point and low penetration value, engineered for applications that demand durability, temperature resistance, and reliable waterproofing performance. It is widely used across roofing systems, industrial insulation, pipe coating, and general construction.
Applications of Oxidized Bitumen 115/15
Blown Asphalt 115/15 is widely used in:
- Roofing membranes and waterproofing systems
- Industrial insulation and sealing
- Pipe coating and corrosion protection
- Asphalt-based adhesives and mastics
- Expansion joints and crack sealing
This grade is particularly well-suited to applications requiring high thermal resistance and structural stability.
How Oxidized Bitumen 115/15 Compares to Other Grades
Compared to lower softening point grades such as 85/25 or 95/25, Blown Asphalt 115/15 offers higher temperature resistance, greater hardness, and better performance in extreme climates. This combination of properties makes it ideal for demanding industrial applications requiring maximum structural stability.
Common Industries Using Oxidized Bitumen 115/15
Oxidized Bitumen 115/15 is widely used across the roofing and waterproofing industry, oil and gas pipeline coating, and industrial insulation manufacturing. Its high softening point also makes it a preferred choice for producing bitumen-based adhesives and mastics used in construction joints and expansion gaps, particularly in hot-climate regions where lower-grade bitumen would soften and lose structural integrity.
Why Softening Point Matters for This Grade
The softening point of Oxidized Bitumen 115/15 (110–120°C) is one of its most important properties, directly affecting how the material performs under heat exposure. A higher softening point means the material resists deformation and flow at elevated temperatures, making it especially suitable for roofing applications in hot climates and industrial settings where surfaces may reach high temperatures during operation or direct sun exposure.
Export and Supply of Oxidized Bitumen 115/15
RAHA Oil supplies Blown Asphalt 115/15 to international markets across Africa (Kenya, Djibouti, Ghana), the GCC (UAE, Saudi Arabia, Oman), and Asia (India, Malaysia, Indonesia). Our export services include SGS or third-party inspection, complete COA, TDS, and MSDS documentation, flexible FOB and CFR terms, and fast loading from UAE ports.
Storage and Handling Recommendations
Oxidized Bitumen 115/15 should be stored in a dry, covered area away from direct sunlight and moisture to preserve its properties. Due to its high softening point, the material remains hard and stable at ambient temperature, making long-term storage straightforward compared to softer bitumen grades. Before application, it should be heated gradually and evenly to avoid localized overheating, which can affect performance consistency.
Quality Control and Inspection
All shipments of Oxidized Bitumen 115/15 are tested and controlled before delivery to ensure compliance with international standards. This includes a laboratory test report (COA), third-party inspection through SGS when requested, visual inspection during loading, and full supporting documentation for every order.
