Oxidized (Blown) Bitumen
Oxidized (Blown) Bitumen
Oxidized Bitumen, also known as Blown Bitumen or Blown Asphalt, is a specially modified bituminous material produced by passing air through hot penetration-grade bitumen. This controlled oxidation process changes the physical and chemical properties of the material, resulting in higher softening points, improved resistance to temperature changes, and greater stability in demanding applications.
Quality requirements for oxidized and blown asphalt products can vary depending on their intended application.
For roofing and waterproofing applications, ASTM D312/D312M specifies requirements for asphalt used in roofing and covers properties such as softening point, penetration, flash point, ductility, and solubility.
What Is Oxidized Bitumen?
The production process involves blowing air through heated bitumen under controlled conditions. During this process, the material undergoes oxidation, which increases its softening point and modifies its penetration characteristics.
Compared with conventional paving grades, blown grades generally offer greater resistance to heat and deformation. Their specific properties depend on the production conditions and the selected grade.
Different grades are available to meet the requirements of various industrial and construction applications. Asa Bitumen can provide technical specifications and product documentation based on the customer’s requirements.
Blown Bitumen Grades
Blown bituminous products are commonly identified by their softening point and penetration range. For example, grades such as 85/25, 90/10, 115/15, and 150/5 are used for different applications.
The first number generally represents the approximate softening point, while the second indicates the penetration value. Selecting the appropriate grade depends on operating temperature, application method, required flexibility, and performance requirements.
Our team can help buyers select a suitable grade based on their technical specifications and destination market.
Bitumen Oxidized 85/25
Grade 85/25 offers a balanced combination of softening point and penetration, making it suitable for waterproofing, roofing, insulation, and various industrial applications. Its good thermal stability and resistance to deformation provide reliable performance under demanding operating conditions.
Bitumen Oxidized 95/25
Grade 95/25 is designed for applications requiring improved resistance to heat and deformation. With a higher softening point, it provides dependable performance in waterproofing membranes, coatings, sealants, and industrial products exposed to elevated temperatures.
Bitumen Oxidized 115/15
Grade 115/15 provides a higher softening point and lower penetration for applications requiring greater hardness and thermal stability. It is commonly used in waterproofing, pipe coatings, insulation, sealants, and industrial applications where resistance to heat is essential.
Factors to Consider When Choosing a Grade
Selecting the right grade depends on the required balance between hardness, temperature resistance, and flexibility. Products with a higher softening point can be more suitable for applications exposed to elevated temperatures, while grades with higher penetration may provide greater flexibility. The operating environment, application method, and required service life should therefore be considered before selecting a specification.
For international buyers, it is also important to confirm the required technical parameters, packaging method, and applicable quality requirements before placing an order.
Why Choose the Right Blown Grade?
Different applications require different levels of hardness, penetration, and temperature resistance. Choosing a suitable specification can improve product performance and help reduce problems during processing or service. For this reason, buyers should consider more than price when comparing suppliers and grades.
When requesting a quotation, providing the required grade, quantity, destination port, packaging preference, and technical specification allows the supplier to prepare a more accurate offer. Asa Bitumen works with international buyers to provide product information and commercial quotations based on their specific requirements.
Applications of Blown Bitumen
This material is widely used in applications where thermal stability, durability, and resistance to deformation are important.
Common applications include:
- Waterproofing membranes and roofing materials
- Pipe coating and corrosion protection
- Cable and electrical insulation
- Adhesives and sealants
- Construction and building materials
- Industrial coatings
- Soundproofing and insulation products
- Chemical-resistant applications
Its relatively high softening point makes it particularly suitable for products exposed to elevated temperatures or demanding operating conditions.
Quality and Performance
The quality of blown bituminous materials depends on carefully controlled production conditions and compliance with the required technical specifications.
Key parameters such as penetration, softening point, solubility, and other quality indicators help determine whether a grade is suitable for a particular application. Asa Bitumen works with buyers to provide products that meet their required specifications and quality standards.

What is Oxidized Bitumen?
It is a bituminous material produced by passing controlled air through hot penetration-grade bitumen. This process increases the softening point and changes its penetration and temperature resistance, making it suitable for various industrial applications.
What do the numbers in grades such as 85/25 mean?
The first number generally indicates the approximate softening point, while the second represents the penetration value. For example, 85/25 refers to a softening point around 85°C and penetration around 25 dmm.
What are the main applications of blown asphalt?
It is used in waterproofing, roofing, pipe coatings, sealants, insulation, corrosion protection, electrical applications, and various industrial products where thermal stability and resistance to deformation are required.
Which grades are available from Asa Bitumen?
Asa Bitumen can supply different grades according to customer requirements, including commonly requested specifications such as 85/25, 95/25, and 115/15. Availability may depend on the required quantity and technical specification.
How is the right grade selected?
What factors affect the Oxidized Bitumen Price?
The price depends on the selected grade, order quantity, packaging, origin, destination, freight costs, and current market conditions. For an accurate quotation, buyers should provide the required grade, quantity, and destination.
What is the difference between 85/25, 95/25, and 115/15?
