OXIDIZED BITUMEN 90/40 – PREMIUM BLOWN ASPHALT
RAHA Oil is a trusted supplier and exporter of Oxidized Bitumen 90/40, based in Dubai, United Arab Emirates, serving industrial, construction, and trading customers across the UAE, GCC, Africa, Asia, and worldwide. Our Oxidized Bitumen 90/40 is manufactured to international standards and offers superior thermal performance, adhesion, and durability.
WHAT IS OXIDIZED BITUMEN 90/40?
Oxidized Bitumen 90/40 is a high-quality blown asphalt produced by passing hot air through selected petroleum bitumen (usually 60/70 grade) under controlled conditions without any catalyst. This air-blowing process raises its softening point, enhances stability during melting, and provides stronger rubber-like properties compared to penetration grade bitumen. The grade “90/40” indicates the midpoint of its softening point (85–95 °C) and penetration range (35–45 dmm), giving the material an ideal balance of rigidity and flexibility for industrial applications. Oxidized Bitumen 90/40 is a solid or semi-solid black material that becomes liquid when heated and is widely used in the Mediterranean region—especially in Morocco—for waterproofing, coatings, adhesives, insulation, and various construction and industrial uses. It is produced through continuous or staggered blowing processes, and its properties are measured according to ASTM D36 for softening point and ASTM D5/IP49 for penetration.
USES OF OXIDIZED BITUMEN 90/40
There are many uses of this grade of oxidized bitumen but it is mainly used for industrial applications such as roof felts, waterproofing, roof and floors anti-rust pipe coating, anti-slip layer compound, sound dampening felts, coats for automobile industry, joint filling compounds, sealants and bituminous mastic. Oxidized bitumen 90/40 is used in the chemical, fuel, paints, lacquers, varnishes, paper-pulp-board, textile processing, road construction, pavement, crack seals and repairs, civil works, roofing, construction industries; sealing and insulating buildings, adhesive, construction materials additive, dust-binding, insulating and impregnating agent, and also to manufacture rubber and plastic products. Oxidized Bitumen 90/40 products are also used in asphalt-based paints for corrosion protection of metals, in lining public works structures, adhesives in electrical laminates, base for synthetic turf. Typical uses for Oxidized Bitumen 90/40 are for water-proof application and corrosion resistance for pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing, caulking, mastics, and damp proofing. This grade of bitumen can be used for insulation and isolation in bitumen membrane sheets. It is also used in the automobile industry for car undercoating as it is proven to be an excellent water-proofing, dust proofing and also noise proofing material.

HANDLING & SAFETY GUIDELINES
Oxidized Bitumen 90/40
Proper heating and handling are crucial:
- Heating: Oxidized Bitumen 90/40 should be gradually heated (typically up to 220–230 °C) before application.
- Safety: Wear heat-resistant gloves, goggles, and protective clothing. Avoid overheating, which can degrade properties and release fumes.
- Storage: Store in a cool, dry place away from open flames. Follow MSDS instructions for safe storage and handling
