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 first main difference between these two types of bitumen is their softening point and penetration rate. Oxidized Bitumen 115/15 bitumen with a softening point of 115°C and a penetration of 15/10 mm is generally harder and more resistant to deformation. This feature makes 115/15 bitumen ideal for use in high-temperature environments and in conditions that require thermal stability and resistance to extreme temperature changes.
On the other hand, oxidized bitumen 85/25 with a softening point of 85 degrees Celsius and a penetration of 25 tenths of a millimeter is more flexible and suitable for use in environments with more moderate temperatures. This feature makes bitumen 85/25 perform better in projects that require more flexibility and the ability to adapt to more temperature changes.
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.
