What is Bitumen 115/15?

Oxidized Bitumen 115/15 is an air-blown bitumen grade with a softening point near 115°C and a penetration value around 15 (0.1 mm). Among the hardest oxidised grades produced, it offers exceptional rigidity, minimal thermal sensitivity, and outstanding resistance to deformation in extreme heat and demanding industrial conditions.

Oxidized Bitumen 115/15 is widely used in roofing felts, waterproofing membranes, and industrial protective coatings exposed to hot climates and elevated surface temperatures. Its hardness and high softening point also make it well suited for heavy-duty pipeline coatings, road construction additives, and demanding pavement applications worldwide.

Black Rock Bitumen supplies Oxidized Bitumen 115/15 tested to ASTM standards, ensuring consistent softening point, penetration, and hardness across every shipment. Sourced from certified refineries and shipped through our Dubai logistics hub, our Oxidised Bitumen 115/15 delivers dependable, export-grade performance for the harshest industrial environments worldwide.

    Frequently Asked Questions.

    Oxidized Bitumen Grade 115/15 is a high-softening, low-penetration bitumen designed for superior waterproofing, insulation, and industrial durability.

    Bitumen 115/15 is a very hard oxidized bitumen with a softening point of 115°C and penetration of 15 dmm, designed for extreme-heat industrial applications.

    It is used in cable filling and insulation compounds, battery sealing compounds, industrial mastics, and other applications requiring resistance to very high temperatures.

    The 115°C softening point results from an extended air-blowing (oxidation) process, producing a very hard, heat-stable bitumen for specialized industrial uses beyond standard roofing or pipe coating grades.

    Bitumen 115/15 has an even higher softening point than 105/15, making it suited to more extreme temperature environments and specialty industrial compounds.

    Application temperatures typically range from 215–235°C for hot-applied industrial systems, depending on the process; care should be taken to avoid exceeding recommended limits to prevent premature oxidation.

    Bitumen 115/15 is typically tested per ASTM D312 for softening point, penetration, and related specialty industrial specifications.

    Store in a cool, dry, covered area away from heat sources, in sealed drums or blocks to preserve product integrity.
