Oxidized Bitumen 90/10 Definition
Oxidized Bitumen 90/10 refers to a specific grade of bitumen that has undergone a controlled oxidation process. The numbers “90/10” typically indicate the penetration and softening point properties of the bitumen.
In this case:
– “90” represents the penetration value, which indicates the hardness or consistency of the bitumen. A lower penetration value indicates a harder bitumen.
– “10” represents the softening point, which is the temperature at which the bitumen softens under specific conditions. A higher softening point indicates a bitumen with greater temperature resistance.
Oxidized Bitumen 90/10 is commonly used in various applications such as road construction, waterproofing, and roofing, where durability and temperature resistance are important factors. The controlled oxidation process alters the properties of bitumen to enhance its characteristics for specific applications.

Recommendations for Handling / Storage Blown Asphalt 90/10
Handling and storing Oxidized Bitumen 90/10 requires careful attention to ensure its quality and usability. Here are some recommendations:
- Storage Temperature: Store Blown Asphalt 90/10 in a covered area away from direct sunlight and heat sources to prevent overheating and degradation. The recommended storage temperature is typically between 15°C to 25°C (59°F to 77°F).
- Avoid Contamination: Prevent contamination by storing Oxidized Bitumen 90/10 away from substances such as solvents, fuels, and acids. Ensure the storage area is clean and free from debris.
- Ventilation: Ensure adequate ventilation in the storage area to prevent the accumulation of fumes and maintain a safe working environment.
- Protection from Moisture: Protect the material from moisture by storing it in sealed containers or tanks. Moisture can degrade the quality of Oxidized Bitumen 90/10 and affect its performance in asphalt mixtures.
- Handling Precautions: When handling Oxidized Bitumen 90/10, use appropriate personal protective equipment, including gloves, safety glasses, and protective clothing, to prevent skin contact and inhalation of fumes.
- Avoid Overheating: Do not expose Oxidized Bitumen 90/10 to temperatures above its softening point during storage or handling to prevent premature aging and degradation.
- Segregation Prevention: Avoid segregation during transportation and handling by using proper equipment and procedures to maintain uniformity and consistency of the material.
Technical Advantages of Blown Bitumen 90/10
Blown Bitumen 90/10 offers several technical advantages:
- High Softening Point: Blown bitumen has a higher softening point compared to regular bitumen, making it suitable for applications requiring greater resistance to temperature fluctuations and deformation.
- Improved Durability: Its enhanced properties contribute to improved durability, making it ideal for heavy traffic areas and extreme weather conditions.
- Enhanced Cohesion and Adhesion: Blown bitumen exhibits improved cohesion and adhesion properties, resulting in better bonding with aggregates and surfaces, leading to longer-lasting pavements.
- Resistance to Aging and Oxidation: Blown bitumen tends to resist aging and oxidation better than conventional bitumen, prolonging the life of pavement surfaces.
- Flexibility and Versatility: It offers flexibility in formulation and application, allowing for customized blends tailored to specific project requirements.
- Reduced Rutting and Rutting Resistance: Blown bitumen’s higher viscosity and stiffness help reduce rutting, enhancing the overall performance of asphalt pavements.
