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)

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

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.
A note must be taken of the maximum safe handling temperature of 230 C and this should not be abused. Bitumen is a poor conductor of heat, consequently, control of the heating phase is of paramount importance.
The Oxidized Bitumen material should be broken up prior to placement in the boiler. This exposes a larger surface area to the heat and encourages a more even heating regime. Without the larger exposed surface area, aggressive heating at the base and sides of the boiler may well result in localized overheating, altering the characteristics of the BituKim modified bitumen, and potentially causing thermal cracking of the bitumen, creating the release of low lash vapors. The flashpoint of the oxidized bitumen then becomes irrelevant; as these low flash vapors determine the fire risk.
Melted bitumen should not be left in the boiler and reheated from cold, as there is then a high potential for localized overheating around the heating area (lack of convection means poor heat transfer) and potential development of a pressurized pocket of low flash vapors.
Be aware of the placement of any temperature monitoring or control devices. As a result of the poor thermal conductivity of the bitumen, a thermometer in the bitumen some distance from the heat source could read significantly different (even hundreds of degrees) from the true temperature of the bitumen near the heat source. Blown asphalt 90/40 has 10 years of validity with multi-time heating and cooling.

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.
