Uses of Oxidized Bitumen 85/25 in Industrial and Construction Sectors
Oxidized Bitumen 85/25 is an essential material in modern construction and industrial engineering. Engineered through an air-blowing process, this specialized grade delivers exceptional thermal resistance, waterproofing, and mechanical durability. Discover the key uses of Oxidized Bitumen 85/25 across infrastructure, roofing, joint sealing, and protective pipe coatings.
In this blog, we delve into the uses and benefits of Blown bitumen 85/25 highlighting its importance in modern infrastructure projects. Furthermore, we spotlight Peak Universal Business as a trusted supplier of premium quality Oxidized Bitumen.
What Is Oxidized Bitumen 85/25?
Oxidized Bitumen 85/25 is an engineered asphalt grade produced by passing hot air through vacuum bottom residue at 240 to 320 degrees Celsius. It is characterized by a softening point of approximately 85 degrees Celsius and a penetration value of 20 to 30 dmm, providing enhanced thermal stability and water resistance.
Softening Point: ~85°C
Penetration Value: ~25 dmm
This grade is specifically engineered for use where controlled melting, water resistance, and strong binding characteristics are required.
The softening point refers to the temperature at which the bitumen softens under specified conditions, while penetration denotes the depth to which a standard needle penetrates the bitumen sample under specific conditions of loading, time, and temperature. Blown Bitumen 85/25, with its higher softening point and lower penetration value, exhibits enhanced resistance to temperature variations and improved durability compared to conventional bitumen grades.
What are the technical specifications of blown bitumen 85/25?
| Property | Unit | Typical Value |
|---|---|---|
| Softening Point (R&B) | °C | 85 ± 5 |
| Penetration @25°C | dmm | 20 – 30 |
| Flash Point | °C | > 250 |
| Ductility @25°C | cm | > 1.5 |
| Solubility in CS₂ | % | > 99.5 |
| Loss on Heating | % | < 0.5 |
What are the main uses of Oxidized Bitumen 85/25?
Oxidized Bitumen 85/25 is primarily utilized across road and bridge expansion joints, structural waterproofing systems, pavement preservation treatments, and industrial protective coatings. Its structural hardness and low penetration prevent moisture intrusion, resist rutting, and protect steel or pipelines against aggressive environmental corrosion.
How does Oxidized Bitumen 85/25 perform in road expansion joints?
One of the primary applications of Oxidized Bitumen 85/25 is in road construction and maintenance. This grade of bitumen is commonly used as a binder in asphalt mixes for road surfaces. Its superior resistance to rutting and cracking makes it ideal for high-traffic areas and regions with extreme climatic conditions.
The modified properties of Blown Asphalt 85/25 enhance the longevity and performance of road pavements, ensuring smoother and safer transportation networks.
Why is bitumen 85/25 used in waterproofing and pipe coating?
Another significant application of Oxidized Bitumen 85/25 is in waterproofing systems for various structures. Whether it’s roofing membranes, underground tanks, or bridge decks, this specialized bitumen provides excellent waterproofing capabilities. Its high softening point and low penetration ensure superior adhesion and resistance to water ingress, protecting structures from moisture-related damage and extending their service life.
Pavement Preservation:
Pavement preservation techniques aim to prolong the lifespan of existing road surfaces through preventive maintenance strategies. Blown bitumen 85/25 plays a crucial role in pavement preservation treatments such as chip seals and micro surfacing. By rejuvenating and sealing the existing pavement surface, this grade of bitumen helps prevent moisture intrusion, oxidation, and the formation of cracks, thereby extending the life of the road infrastructure and reducing overall maintenance costs.
Bituminous Paints and Coatings:
Oxidized Bitumen 85/25 finds applications in industrial coatings for corrosion protection and insulation purposes. Its excellent adhesion properties make it suitable for coating pipelines, tanks, and structural steel components exposed to harsh environments. Additionally, its resistance to UV radiation and chemical degradation enhances the durability and performance of protective coatings, ensuring long-term asset protection.
