What Is Oxidized Bitumen 105/15?
Oxidized Bitumen 105/15 is a semi-solid, high-softening-point blown asphalt manufactured through controlled air-blowing of petroleum bitumen. This process increases hardness, heat resistance, and durability, making it an ideal material for industrial, waterproofing, roofing, and paving applications. Raha Oil supplies Blown Asphalt 105/15 from Dubai, UAE, with exports to the GCC, Africa, Asia, and global markets, backed by customized packaging and fast delivery.
Oxidized Bitumen 105/15 is produced by air-blowing base bitumen to a softening point of approximately 105°C and a penetration value of approximately 15 (0.1 mm). It remains solid at ambient temperature and becomes workable when heated, offering excellent thermal stability, strong adhesion to different surfaces, and high resistance to water, chemicals, and aging — even in harsh climates.
Key Benefits of Oxidized Bitumen 105/15
Oxidized Bitumen 105/15 offers high heat resistance suitable for hot climates, excellent waterproofing performance, and strong adhesion and durability. It resists chemicals, salts, and UV exposure, remains stable in storage with a long service life, and is easy to melt and apply. The grade maintains flexibility and bonding strength even after long-term exposure to external conditions.
How Oxidized Bitumen 105/15 Is Manufactured
After preheating, the short residue is introduced into the blowing column just below the normal liquid level. Air is blown through the bitumen by means of an air distributor located at the bottom of the column. The air acts not only as a reactant but also serves to agitate and mix the Blown Asphalt 105/15, increasing both the surface area and the rate of reaction. The bitumen absorbs oxygen as air ascends through the material. Steam and water are sprayed into the vapor space above the bitumen level — steam to suppress foaming and dilute the oxygen content of waste gases, and water to cool the vapors and prevent after-burning and coke formation.
Applications of Oxidized Bitumen 105/15
Oxidized Bitumen 105/15 is widely used across construction, infrastructure, and industrial sectors. In construction and waterproofing, it serves in roofing sheets and waterproof membranes, foundation damp-proofing, basement and concrete protection, and joint sealing and crack filling. In road and infrastructure projects, it is used in asphalt mix modification, expansion joints, and bridge construction. Industrially, it is applied in pipe coating and corrosion protection, adhesives and mastics, electrical insulation materials, protective coatings, and automotive undercoating.
This grade is ideal wherever high thermal stability and reliable waterproofing performance are required.
Handling and Storage of Oxidized Bitumen 105/15
Blown Asphalt 105/15 should be heated gradually using indirect heating methods, within a typical working temperature range of 180–220°C, without exceeding the recommended temperature during application. Overheating or re-heating from cold should be avoided. The material should be stored in a cool, dry place away from direct sunlight, and personal protective equipment (PPE) is recommended during handling. MSDS documentation is available upon request.
Technical Advantages and Packaging Options
Oxidized Bitumen 105/15 offers strong technical advantages: durability, flexibility, water resistance, and chemical stability. The grade is designated by two numbers indicating its softening point and penetration range — in this case, a softening point of approximately 105°C and a penetration value of approximately 15 (0.1 mm) — produced in compliance with ASTM standards.
Raha Oil supplies Blown Asphalt 105/15 in steel drums, Kraft paper bags, meltable PE bags, and bulk or container loading, with customized packaging and labeling available based on order size and export requirements.
