What Is Oxidized Bitumen 115/15?

Oxidized Bitumen 115/15 is a thermoplastic hydrocarbon material produced by blowing hot air through penetration grade bitumen (typically 60/70) at controlled temperatures of 240–270°C. This air-blowing process — also known as oxidation — increases the softening point and reduces the penetration value, producing a harder, more temperature-resistant material than standard paving bitumen. The designation “115/15” refers to two key properties: a softening point of 115°C (Ring & Ball method) and a penetration of 15 tenths of a millimeter (dmm) at 25°C.

Oxidized Bitumen 115/15 is the single most produced and traded grade of oxidized (blown) bitumen worldwide. It accounts for the majority of global oxidized bitumen demand due to its exceptional combination of high-temperature stability, waterproofing performance, adhesion, and chemical resistance. It is the standard specification for roofing felt manufacturing, modified bitumen membrane production, pipe anti-corrosion coatings, and industrial sealant applications across the Middle East, Africa, Europe, and Asia.

How Is Oxidized Bitumen 115/15 Produced?

Oxidized Bitumen 115/15 is manufactured through a controlled air-blowing process applied to penetration grade bitumen 60/70. The process transforms the base bitumen’s chemical and physical properties by increasing its molecular weight, reducing temperature susceptibility, and raising the softening point. The four stages of production are:

🛢️

Base Bitumen Heating

Penetration grade bitumen 60/70 is heated to 240–270°C in a closed oxidation vessel under controlled conditions.

💨

Air Injection

Compressed hot air is injected through the heated bitumen at a controlled rate. Oxygen reacts with bitumen molecules in an exothermic reaction.

⚗️

Oxidation & Hardening

The reaction increases molecular weight and cross-links polymer chains, raising softening point to ~115°C and reducing penetration to ~15 dmm.

✅

QC Testing & Packing

Product is tested against ASTM D312 / EN 13304 specifications. COA issued and material packed in kraft bags, meltable bags, or drums.

Oxidized Bitumen 115/15 Applications

🏠

Roofing Felt & Membrane Manufacturing

The primary application globally. Used as the base impregnant for roofing felt and as the coating compound in modified bitumen membranes (SBS and APP). High softening point prevents flow at elevated roof temperatures.

💧

Waterproofing & Damp-Proofing

Applied to foundations, basements, bridge decks, tunnels, and retaining walls as a waterproofing barrier. Excellent adhesion to concrete and masonry combined with impermeability to water makes it ideal for below-grade applications.

🔩

Pipe Anti-Corrosion Coating

Used as anti-corrosion wrapping for buried steel pipelines (oil, gas, water). Applied as hot-applied coating or in cold tape form. Resistant to soil chemicals, moisture, and cathodic disbonding. Complies with DIN 30672 and EN 10300.

🚗

Automotive Underbody Sealants

Applied as sound-dampening and anti-corrosion undercoating on vehicle chassis and body panels. High hardness and adhesion to metal substrates, combined with vibration-damping properties, make it the standard specification for OEM automotive sealing.

⚡

Electrical Cable & Joint Protection

Used in cable joint filling compounds, electrical insulation tapes, and transformer oil additives. High dielectric strength and chemical resistance make oxidized bitumen 115/15 suitable for high-voltage cable protection applications.

🏭

Industrial Flooring & Pavement

Applied in bituminous industrial floor coatings, anti-slip layer compounds in the piling industry, and port terminal pavement in very hot climates. Also used in hydraulic structures, dam facings, and canal linings requiring permanent waterproofing.

🎾

Synthetic Turf Base & Sports Surfaces

Used as the binder in shock-pad layers under artificial grass systems for football pitches, running tracks, and tennis courts. The combination of hardness and rubber-like elasticity provides the required cushioning and drainage properties.

🎨

Bituminous Paints & Coatings

Used as the base in bitumen-based anticorrosion paints and lacquers for metal structures, storage tanks, and public works infrastructure. Dissolved in solvent to produce black bituminous paint for structural steel protection.

🌊

Marine & Hydraulic Applications

Applied in marine mastic, harbor sealing, and offshore structure protection. Used in grouted mattresses for scour protection and in canal and reservoir linings. Resists saltwater, wave action, and UV degradation in coastal environments.

Frequently Asked Questions — Oxidized Bitumen 115/15

What does 115/15 mean in oxidized bitumen?
The designation 115/15 refers to two key physical properties: the first number (115) is the softening point in °C measured by the Ring & Ball method (ASTM D36), and the second number (15) is the penetration value in tenths of a millimeter (dmm) at 25°C under 100g load for 5 seconds (ASTM D5). So Oxidized Bitumen 115/15 has a softening point of 110–120°C and a penetration of 10–20 dmm — indicating a very hard, high-temperature-resistant material.
What is the difference between oxidized bitumen and penetration grade bitumen?
Penetration grade bitumen (such as 60/70 or 80/100) is produced directly from crude oil distillation and is used primarily for road paving. Oxidized bitumen is produced by blowing hot air through penetration grade bitumen, which raises the softening point, reduces penetration, and changes the bitumen from a temperature-susceptible paving binder to a harder, rubber-like material suitable for roofing, waterproofing, and industrial applications. Oxidized bitumen is significantly harder and more heat-resistant than penetration grade bitumen.
What is the softening point of oxidized bitumen 115/15?
The softening point of Blown Asphalt 115/15 is 110–120°C, measured by the Ring & Ball method (ASTM D36 / EN 1427). This high softening point means the material remains solid and structurally stable at temperatures well above typical ambient conditions — making it ideal for roofing applications where surface temperatures can exceed 80°C in hot climates.
What standards does Blown Asphalt 115/15 comply with?
Oxidized Bitumen 115/15 from Zumrut International complies with ASTM D312 Type III (American standard), EN 13304 (European standard for oxidized bitumen used in roofing), and ISIRI 286 (Iranian standard). Each shipment is accompanied by a full Certificate of Analysis (COA) from an accredited laboratory confirming compliance with the applicable standard, as well as a Material Safety Data Sheet (MSDS).
What is the melting temperature for oxidized bitumen 115/15?
Oxidized Bitumen 115/15 should be melted at 160–180°C for application. The maximum safe heating temperature is 220°C — above this, the material approaches its flash point (≥250°C) and thermal degradation may begin. Always use indirect heating (steam or hot oil) rather than direct flame when melting. Refer to the MSDS for full safety handling guidelines.
What is the difference between oxidized bitumen 115/15 and 85/25?
Oxidized Bitumen 115/15 is harder, with a higher softening point (110–120°C vs 80–90°C for 85/25) and lower penetration (10–20 vs 20–30 dmm). Grade 115/15 is preferred for roofing felt impregnation, pipe coating, and automotive applications where maximum temperature resistance is required. Grade 85/25 is softer and more flexible, making it better suited for cold-climate waterproofing membranes and applications requiring greater ductility.
What is the HS code for oxidized bitumen 115/15?
Oxidized Bitumen 115/15 is classified under HS Code 2713.20 — Petroleum bitumen, under Chapter 27 (Mineral fuels, mineral oils and products of their distillation). This same code applies to all oxidized/blown bitumen grades. In some countries this extends to 8 or 10-digit national tariff codes. Always verify with your local customs authority for accurate import duty calculations.
What packing is available for oxidized bitumen 115/15?
Oxidized Bitumen 115/15 is available in 25 kg kraft paper bags, 25 kg meltable polyethylene bags (most popular for plant use), cartons on pallets, 180 kg steel drums, 1,000 kg jumbo bags, and bulk vessel shipments from 2,000 MT upward. The most common export packing for African and Asian markets is 25 kg kraft paper bags loaded in 20ft FCL containers (~800 bags = 20 MT). Meltable bags are preferred by roofing manufacturers who melt the entire bag into the production kettle.
