Specifications of Oxidized Bitumen 90/40:

1. Penetration:
   • Value: 90 dmm (decimillimeters)
   • Description: The penetration value indicates the hardness or softness of the bitumen at 25°C. A penetration of 90 dmm suggests a medium hardness suitable for various applications.
2. Softening Point:
   • Value: 40°C
   • Description: The softening point is the temperature at which the bitumen starts to soften. A softening point of 40°C indicates that the bitumen maintains its consistency at relatively low temperatures, making it suitable for moderate climatic conditions.
3. Viscosity:
   • Value: Varies depending on the testing method (e.g., Dynamic Viscosity)
   • Description: Viscosity measures the thickness or resistance to flow. Oxidized Bitumen 90/40 has a viscosity that is suitable for its applications in road construction and waterproofing.
4. Flash Point:
   • Value: Typically around 250°C (open cup)
   • Description: The flash point indicates the temperature at which the bitumen can vaporize to form a flammable mixture in the air. A high flash point signifies better safety during handling and application.
5. Density:
   • Value: Approximately 1.03 to 1.05 g/cm³
   • Description: The density of bitumen affects its application and performance. The specified range is typical for oxidized bitumens.
6. Solubility in Carbon Disulfide:
   • Value: Typically > 99%
   • Description: This measures the degree to which bitumen is soluble in a specific solvent, which helps in understanding its purity and composition.
7. Penetration Index (PI):
   • Value: Usually in the range of 1 to 3
   • Description: The Penetration Index provides a measure of how the bitumen’s hardness changes with temperature. A low PI indicates that the bitumen will be less sensitive to temperature changes.
8. Elasticity:
   • Value: Not typically specified but can be assessed through various tests
   • Description: Elasticity affects the flexibility of the bitumen, crucial for applications requiring flexibility and resistance to cracking.

General description of Oxidized Bitumen 90/40

Oxidized Bitumen 90/40 is based on petroleum bitumen which is made by blowing bitumen 60/70 by hot air. The most oxidized bitumen usable grade is bitumen 115/15 and 70% of our capacity is dedicated to this grade.
Bitumen 90/40 is a semi-solid oxidized grade of pure petroleum bitumen categorized in polycyclic aromatic hydrocarbons and oxidized bitumen normally used for different purposes in the construction business. Oxidized Bitumen 90/40 has a high softening point and high flash point and it is highly stable during melting.

This grade of oxidized bitumen is highly sought after as it has a high flash point, high softening point, as well as high stability during melting. These properties of bitumen are suitable for many different purposes in the construction business.
Oxidized bitumen 90/40 exhibits predominantly “solid” characteristics at ambient temperatures and provides superior adhesive and waterproofing qualities when heated.

Blown Bitumen 90/40 made by air Blowing Process. Heated Bitumen penetration under a controlled environment is blown with air which controls the oil content in bitumen while it oxidized. Different grades for suited uses are produced. Grades are designated by two numbers to indicate mid-points of softening points. Also, their penetration ranges.

Oxidized Bitumen 90/40  has a different name, Some of these alternative names include:

• Blown Asphalt 90/40
• Blown Bitumen 90/40
• Oxidizing Bitumen 90/40
• Oxidized Asphalt 90/40
• Air Blown Asphalt 90/40
• Air-Rectified Bitumen 90/40

Oxidized Bitumen 90/40 has several usages in the industry

Oil and Gas industries:

• Coating materials for pipelines and pipe joints of Oil Also Gas Pipelines.

Electrical industries:

• The sealant of wire coating

Waterproofing industries:

• Building roofing felts in factories and first materials components who are producing waterproofing roofing felt sheets

Bitumen and Asphalt:

• Road paving, Asphalt, construction.
• Making Sound insulation layers.
• Car tires and lining.

Recommendations for Handling / Storage of Oxidized Bitumen 90/40

• Storage Temperature: Typically stored in a controlled environment to maintain its properties.
• Handling Precautions: Requires careful handling to avoid overheating or contamination.

The heating of packaged bitumen is a critical phase in most of the final uses. Typically, the packaged material is heated and melted in boilers out on site.
However, control at the heating phase is very important in terms of health and safety as well as in maintaining the quality of the product.

Health & Safety of Oxidized Bitumen 90/40

workers should comply with these tips:

• Ventilation: workers anywhere working should have appropriate Ventilation Because Oxidized Bitumen can release fumes when heated, which can be harmful if inhaled.
• Protective Equipment: workers should use heat-resistant gloves, safety shoes, long-sleeved shirts, long trousers, and safety goggles.
• Fire Safety: Workers work with high temperatures for this reason Keep bitumen away from open flames or sparks and have appropriate fire extinguishing equipment on hand.
