Oxidized bitumen 115/15 and oxidized bitumen 85/25 are both types of oxidized bitumen that are used in different industries, but they have many differences in their characteristics and applications.
Softening point and penetration rate
The primary distinctions between these two types of oxidized bitumen lie in their softening points and penetration rates, which significantly influence their performance in different applications.
Oxidized Bitumen 115/15 is harder, with a softening point of 115°C and a penetration rate of 15/10 mm, resulting in minimal deformation. This makes it ideal for high-temperature applications and environments requiring thermal stability and resistance to extreme temperature fluctuations. Its robust structure ensures durability and resistance to harsh conditions, making it particularly well-suited for industrial and construction projects that demand long-lasting performance.
In contrast, Oxidized Bitumen 85/25 has a lower softening point of 85°C and a higher penetration rate of 25/10 mm, offering greater flexibility. This flexibility allows it to perform effectively in medium-temperature environments and applications requiring adaptability to temperature variations. Its ability to expand and contract under variable conditions makes it a valuable choice for projects such as roofing and road paving, where materials must endure both temperature and pressure changes.
The flexibility of 85/25-bitumen also enhances its resistance to structural cracking and softening caused by fluctuating temperatures, ensuring reliable performance in such environments.
Operating temperature
In terms of performance temperature, bitumen 115/15 performs better at high temperatures due to its higher softening point, and for this reason, for applications such as industrial coatings, road construction, and some construction projects that are exposed to direct heat or hot weather conditions. It is suitable. Bitumen 85/25 with a lower softening point and greater flexibility performs better in situations where there is a need for greater flexibility and resistance to temperature changes.
Therefore, this type of bitumen is more useful in projects that require greater adhesion and flexibility against movement and seasonal changes, such as sealants, pipe coatings, and asphalt coatings in moderate temperatures or colder areas.
Flexibility
In terms of flexibility, 85/25 bitumen is more flexible than 15/115 bitumen due to its higher penetration and lower softening point, and it can better withstand mechanical stress and lower temperature. This feature makes 85/25 bitumen more suitable for projects that require flexibility and adaptation to changing conditions.
Conclusion
In general, bitumen 115/15 is more known as bitumen with excellent performance at high temperatures and requires hardness and resistance to extreme temperature changes, while bitumen 85/25 is more flexible in moderate temperature conditions and areas with More temperature changes and the need for better adhesion are used. Finally, the choice of bitumen type depends on the environmental conditions and the specific needs of the project.
