General Description of Oxidized Bitumen 90/15
Oxidized Bitumen 90/15 is a type of bitumen binder commonly used in various construction applications. Here’s a general description:
- Composition: Oxidized Bitumen 90/15 is derived from petroleum and undergoes an oxidation process to modify its properties. It contains hydrocarbons and additives that enhance its performance and durability.
- Characteristics: The “90/15” designation refers to its penetration and softening point characteristics:
– “90” indicates the penetration value of the bitumen, measured in tenths of a millimeter (0.1 mm), at a standard temperature of 25°C. A lower penetration value indicates a harder bitumen.
– “15” denotes the softening point of the bitumen, measured in degrees Celsius (°C). The softening point represents the temperature at which the bitumen softens under specified conditions. A higher softening point indicates greater resistance to deformation at high temperatures. - Properties: Oxidized Bitumen 90/15 typically exhibits increased viscosity, higher softening point, and improved resistance to aging, weathering, and deformation compared to unmodified bitumen. These properties make it suitable for various construction applications where durability and weather resistance are essential.
- Applications: Oxidized Bitumen 90/15 is used in road construction, pavement sealing, waterproofing, roofing, and industrial coatings. It is commonly applied as a binder in asphalt mixtures, surface treatments, crack sealants, joint fillers, and roofing membranes to provide waterproofing, weatherproofing, and structural integrity.
- Handling and Storage: Proper handling and storage are essential to maintain the quality and performance of Oxidized Bitumen 90/15. It should be stored in well-ventilated, dry areas away from direct sunlight, heat sources, and ignition hazards. When handling, appropriate personal protective equipment should be worn to prevent skin contact and inhalation of fumes.

Technical Advantages of Oxidized Asphalt 90/15
Oxidized Asphalt 90/15 offers several technical advantages due to its specific properties and characteristics:
- Enhanced Durability: The oxidation process increases the molecular weight and viscosity of the asphalt, resulting in improved resistance to aging, weathering, and deformation under traffic loads. This enhances the longevity and performance of pavements and other construction applications.
- Higher Softening Point: Oxidized Asphalt 90/15 has a higher softening point compared to unmodified asphalt, making it more resistant to deformation at high temperatures. This property helps prevent softening and rutting in hot climates and high-temperature environments.
- Reduced Penetration: The oxidation process reduces the penetration value of the asphalt, indicating a harder and more viscous material. This improves adhesion to aggregate particles and reduces the risk of bleeding or flushing in asphalt pavements, resulting in better overall performance.
- Improved Weather Resistance: Oxidized Asphalt 90/15 forms a tight and durable waterproofing layer when applied to surfaces, making it highly resistant to moisture infiltration and environmental degradation. This makes it suitable for various construction applications requiring weatherproofing and protection against water damage.
- Enhanced Cohesion: The increased viscosity and hardness of oxidized asphalt improve its cohesion and resistance to deformation, resulting in better structural integrity and stability for construction materials and pavements.
- Versatility: Oxidized Asphalt 90/15 can be used in a wide range of construction applications, including road construction, pavement maintenance, waterproofing, roofing, and industrial coatings, due to its adaptability and compatibility with other materials.
