Blown Asphalt 90/10
Oxidized Bitumen 90/10 is manufactured from carefully selected crude oil sources and refined under controlled operating conditions to ensure consistent quality. The production process involves air-blowing base bitumen (typically Bitumen 60/70) at high temperature, which increases the softening point and reduces penetration compared to standard paving grades.
This careful selection of feedstock and process control is what allows Raha Oil to consistently produce a high-purity, high-performance Blown Asphalt 90/10 grade suitable for demanding industrial and construction applications, meeting the specifications outlined in the technical data sheet below.
Applications of Oxidized Bitumen 90/10
Oxidized Bitumen 90/10 is widely used across construction, industrial, and specialty applications:
Construction and Infrastructure: Roofing felts and waterproof membranes, foundation and concrete protection, and joint fillers and crack sealing.
Industrial Coatings: Pipe coatings and corrosion protection, bituminous paints, mastics, and adhesives, and thermal insulation bonding.
Specialized Applications: Anti-slip and acoustic panels, carpet-backing and flooring, automotive undercoating (waterproofing and noise reduction), electrical insulation components, and bituminous marine mastics for oil and gas pipeline joints.
This grade is also used in sealing expansion joints, repairing joints and cracks, fixing parquet floors, and bonding wet briquettes.
Oxidized Bitumen 90/10 vs. Other Oxidized Grades
Oxidized Bitumen 90/10 is one of the hardest grades in the Oxidized Bitumen family, with a low penetration range (5–15) similar to 115/15 or 105/15, but with a slightly lower softening point (85–95°C). This combination makes it extremely rigid and resistant to deformation, positioning it among the top choices for applications where maximum hardness and minimal flow are required, such as sealing and marine mastic production.
Why Oxidized Bitumen 90/10 Is Ideal for Marine and Pipeline Sealing
The extreme hardness and low penetration of Blown Asphalt 90/10 make it particularly well-suited for bituminous marine mastic used in oil and gas pipeline joint sealing, where resistance to deformation under pressure and long-term exposure to harsh marine environments is critical. Its rigidity also supports applications in acoustic panels and carpet-backing, where dimensional stability is important.
Key Advantages of Oxidized Bitumen 90/10
Blown Asphalt 90/10 offers high thermal resistance for hot environments, durable and long-lasting performance, excellent waterproofing and chemical stability, and strong adhesion and bonding properties. Compared to paving grade bitumen, it shows reduced temperature susceptibility, a more solid nature at ambient temperatures, and a high penetration index.
Storage and Handling Recommendations
Blown Asphalt 90/10 should be stored in a cool, dry area away from direct sunlight and open flames. Because of its low penetration and high hardness, it remains very stable at ambient temperature, making long-term storage straightforward. Before heating, the material should be broken into manageable pieces to ensure even, controlled temperature distribution.
Frequently Asked Questions - FAQ
It is used mainly in roofing, waterproofing, pipe coating, automotive undercoating, and as a base for bituminous marine mastics for pipeline joints.
Oxidized Bitumen 90/10 has a softening point of 85–95°C and a penetration value of 5–15 (0.1 mm), as confirmed by ASTM D36 and ASTM D5 testing.
It should be gradually heated in a boiler, typically not exceeding 230°C, avoiding overheating which can degrade its properties.
