Oxidized bitumen, also known as blown or air-blown bitumen or blown asphalt, is a type of bitumen modified by blowing air through it at elevated temperatures. This process increases its viscosity and softening point, making it suitable for various applications.
OXIDIZED BITUMEN (BLOWN ASPHALT) is produced by either continuous or Staggered Blowing Process. Heated Penetration Grade BITUMEN under controlled environment is blown with air which controls the oil content in the bitumen while it oxidized.
The different oxidized bitumen grades for suited applications produced are designated by two numbers to indicate the mid-points of their softening point and penetration ranges.
Produced oxidized bitumen (Blown asphalt) is commonly used in the construction and waterproofing industry due to its excellent waterproofing and adhesive properties.
Petro Tar Company is Manufacturer of OXIDIZED BITUMEN that produce, export, supply and sell all grades of OXIDIZED BITUMEN (HARD BITUMENOXIDISED BITUMEN) 99.5% Pure and without Gilsonite and just by air blowing, specially PURE OXIDIZED BITUMEN R90/40 by Competitive price. We offers High Quality and Purity Iranian oxidized bitumen 90/40 (Hard bitumen 90/40) made according to ASTM STANDARD in PETRO TAR Company refinery.

OXIDISED BITUMEN 90/40 or BLOWN GRADE BITUMEN 90/40 has a wide variety of industrial applications:
–  Roofing, flooring and waterproofing: Oxidized bitumen is commonly used as a waterproofing material in roofing & flooring applications. It provides a durable and weather-resistant barrier, making it suitable for flat roofs, built-up roofing systems, and modified bitumen roofing.  As bonding Bitumen for roofing sheets memberane Roll and pour application of bitumen felts. Foundation, Basement, Under_layments,  production of roofing felts, roll and pour application of bitumen felts, under carriage sealant, leak_proof layers, lining of dams, Canals and pools,  Marine Mastics.
  – Paving and road construction: In road construction and paving, oxidized bitumen or blown asphalt is used as a binder in hot mix asphalt (HMA) or warm mix asphalt (WMA). The oxidation process increases its stiffness and resistance to temperature variations, making it ideal for road surfaces that experience heavy traffic and high temperatures. Road resurfacing and repair, Construction Projects.
  – Joint and crack sealants: Oxidized bitumen or hard bitumen is employed as a sealant for filling joints and cracks in concrete or asphalt pavements. It helps prevent water infiltration and protects the underlying structure from moisture-related damage. Insulation, Isolation, Bridge Joints, Sealing of laps and joints of various bituminous felts and membranes.
 – Pipe coating and drilling: In the oil and gas industry, oxidized bitumen or oxidised bitumen is used for coating pipes to provide corrosion resistance and protect them from environmental factors. Lining of Cannals, dams and pipes,  anti-slip layer compound in the pilling Industry, leakage prevention of tunnels.
 – Paints and coatings: Oxidized bitumen can be used as an additive in paints and coatings to improve their weather resistance and durability. Use as  russt_proof, Sealant Compound, Bituminous paints.
 – Electrical applications: Insulators of electrical material.In some electrical applications, such as cable jointing and sealing, oxidized bitumen is utilized due to its insulating and waterproofing properties.
 – Adhesives and mastics: Oxidized bitumen (oxyde bitume) is employed in the manufacturing of adhesives and mastics, which are used in various construction and industrial applications.
– Soundproofing, damp-proofing and Air & Vapour Control layers: Due to its dense and waterproof nature, oxidized bitumen is used for soundproofing and damp-proofing applications in buildings and structures. Used for production of  sound dampening felts.
