Oxidized Bitumen 85/25


In the ever-evolving world of oil derivatives, Oxidized Bitumen 85/25 has emerged as a crucial player, driving the global synergy in the oil export industry. This specialized form of bitumen holds the key to enhancing infrastructure development, bolstering road construction, and creating a sustainable environment.

Oxidized bitumen 85/25 is a specially processed bitumen product with a higher degree of hardness and durability compared to regular bitumen. It's created by the controlled air-blowing of bitumen derived from crude oil. The numbers "85/25" refer to specific penetration and softening point values, indicating the consistency and thermal stability of the material.

  • Hardness: Oxidized bitumen 85/25 has a significantly higher hardness compared to traditional bitumen. This property makes it ideal for applications requiring improved resistance to deformation under high temperatures, such as road pavements in hot climates.
  • Thermal Stability: The increased softening point of 85/25 makes it more resilient to temperature fluctuations. This makes it suitable for regions with extreme weather conditions, where conventional bitumen might soften and deform.
  • Adhesive Properties: Oxidized bitumen 85/25 has excellent adhesive properties, making it an ideal choice for waterproofing applications. It's commonly used in roofing materials, sealing compounds, and even in pipe coatings to prevent corrosion.
  • Durability: Due to its enhanced properties, oxidized bitumen 85/25 provides a longer service life, reducing the need for frequent maintenance and replacement. This durability is particularly advantageous in high-traffic areas.
  • Road Construction: Oxidized bitumen 85/25 is commonly used in the construction of high-quality, durable road surfaces. Its resistance to softening under heat and deformation under traffic loads ensures that the road remains in good condition for an extended period.
  • Roofing: The adhesive and waterproofing properties of 85/25 make it an excellent choice for roofing materials. It forms a protective layer that shields buildings from water damage and provides longevity to the roof structure.
  • Sealants and Coatings: The adhesive nature of oxidized bitumen 85/25 makes it perfect for various sealing applications. It's used to seal joints, cracks, and as a protective coating for concrete surfaces, providing added durability.
  • Cost-Efficiency: Its durability reduces the need for frequent repairs and replacements, leading to cost savings over the long term.
  • Versatility: It's suitable for a wide range of applications, from road construction to waterproofing.
  • Environmental Compatibility: The longer lifespan of structures using 85/25 means fewer resources are consumed over time.
