Comparing Blown Asphalt 115/15 and 85/25 reveals notable differences in their characteristics and applications, despite both being widely used types of Blown Asphalt across various industries.
Softening point and penetration rate
The key differences between Blown Asphalt 115/15 and 85/25 lie in their softening points and penetration rates, which significantly affect their suitability for various applications.
Blown Asphalt 115/15 is hard and resistant to deformation due to its high softening point of 115°C and low penetration rate of 15/10 mm. It is therefore well-suited to high-temperature applications and environments requiring extreme thermal stability and resistance to extreme temperature fluctuations. It is robust in structure, which makes it tough, reliable, and therefore preferred for industrial and construction activities requiring long-lasting performance.
On the contrary, Blown Asphalt 85/25 has a lower softening point of 85°C and higher penetration rate of 25/10 mm, which makes it more flexible. This property suits medium-temperature applications where materials must be adapted to temperature fluctuations. Its capacity to expand and contract under the influence of changing conditions makes it the best material for roofing and road paving, where the material must undergo both temperature and pressure changes. Additionally, its flexibility enhances resistance to cracking and softening caused by fluctuating temperatures, ensuring dependable performance in such scenarios.
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. Blown Asphalt 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.
Comparing Blown Asphalt 115/15 and 85/25 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 of Comparing Blown Asphalt 115/15 and 85/25
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.
