Complete Explanation About Oxidation Bitumen

What is Oxidation Bitumen?
Oxidation bitumen, also known as blown bitumen or oxidized bitumen, is a type of bitumen that has been treated with air (oxygen) at high temperatures to modify its physical properties. The result is a bitumen that is harder, more durable, and more resistant to temperature fluctuations, making it ideal for specific industrial uses.

How is Oxidation Bitumen Produced?

Production Process:

1. Base Material: The process starts with vacuum residue (a heavy bitumen) from crude oil distillation.
2. Heating: The base bitumen is heated to 240–300°C in a reactor.
3. Air Blowing: Dry air (or oxygen) is blown through the hot bitumen via spargers (pipes with small holes at the bottom of the reactor).
4. Oxidation Reaction: The oxygen reacts with bitumen’s hydrocarbons, especially asphaltenes and resins, forming complex oxygen-containing polymers.
5. Cooling and Storage: The oxidized bitumen is then cooled and stored in drums, blocks, or bulk tanks.

This process increases softening point and viscosity, and reduces penetration.

Key Properties of Oxidized Bitumen

Property /Description

• Softening Point Higher than regular bitumen (typically 85–150°C depending on grade)
• Penetration Lower penetration (harder material), measured in 0.1 mm
• Viscosity Much higher viscosity—more stable at elevated temperatures
• Ductility Reduced ductility; it becomes brittle in cold conditions
• Thermal Stability Excellent; doesn’t flow or drip under high heat
• Water Resistance High water resistance and impermeability

Common grades include 85/25, 90/40, 115/15, 150/5, etc., where the first number is the softening point (°C) and the second is the penetration (dmm).

Applications of Oxidized Bitumen
Oxidized bitumen is used where heat resistance and durability are essential:

Industrial Uses

• Roofing membranes
• Waterproofing of foundations and basements
• Pipe coatings
• Electrical cable joint insulation
• Battery sealing compounds
• Carpet backing
• Rust-proofing and anticorrosive coatings

Construction Uses

• Expansion joints and crack sealants in concrete
• Underlayments for waterproofing
• Sealants in bridge construction

Advantages of Oxidized Bitumen

• High temperature resistance
• Improved adhesion to various substrates
• Stable in storage and application
• Excellent resistance to aging and UV
• Low volatility

Limitations

• Less flexible in cold climates (can crack)
• Not suitable for hot mix asphalt (due to reduced ductility)
• Higher production energy cost due to air blowing

Packaging & Handling

Usually packaged in:

• Kraft paper bags
• PP bags
• Cartons
• Drums
• Blocks or in bulk (for industrial-scale use)

Which grades of oxidized bitumen are most commonly used in the UAE

In the UAE, the most commonly used grades of oxidized bitumen (also known as blown bitumen) are:

1. Grade 85/25
   Softening Point: ~85°C
   Penetration: ~25 dmm
   Use: Waterproofing, pipe coating, roofing membranes
2. Grade 90/40
   Softening Point: ~90°C
   Penetration: ~40 dmm
   Use: Road construction (as an additive), roofing, and sealing applications
3. Grade 115/15
   Softening Point: ~115°C
   Penetration: ~15 dmm
   Use: Electrical cable coatings, industrial flooring, and insulation

The key importance of Oxidized Bitumen UAE

1. Essential for Waterproofing & Insulation
   Oxidized bitumen is widely used in roofing membranes, basement waterproofing, and damp-proof courses, making it a critical material for protecting buildings in the UAE’s harsh, arid climate.
2. High-Temperature Resistance
   Due to the UAE’s extreme summer temperatures, oxidized bitumen is preferred over penetration-grade bitumen for its higher softening point and thermal stability, ensuring long-term performance.
3. Industrial Applications
   Vital in pipe coatings, cable manufacturing, flooring compounds, and sealants, supporting the UAE’s fast-growing industrial and energy sectors.
4. Durability in Harsh Environments
   Offers strong resistance to oxidation, aging, and chemical attacks, making it suitable for both coastal and desert environments.
5. Infrastructure Development
   Integral to road maintenance, bridge joints, and airport runways where flexible, long-lasting sealing and waterproofing are required.
6. Compliance with International Standards
   Oxidized bitumen used in the UAE generally complies with ASTM or EN standards, supporting the country’s push toward high-quality, globally benchmarked construction practices.

Packaging for Oxidized Bitumen Grades in the UAE
