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
he primary distinctions between Blown Asphalt 115/15 and Blown Asphalt 85/25 lie in their softening points and penetration rates, which directly influence their suitability for various applications.
Blown Asphalt 115/15
With a high softening point of 115°C and a low penetration rate of 15/10 mm, Blown Asphalt 115/15 is a hard, durable material highly resistant to deformation. Its robustness makes it ideal for applications that demand extreme thermal stability and resistance to temperature fluctuations. Due to its rigidity, it is widely used in industrial and construction projects requiring long-lasting performance, such as waterproofing, pipe coating, and high-temperature environments.
Blown Asphalt 85/25
In contrast, Blown Asphalt 85/25 has a lower softening point of 85°C and a higher penetration rate of 25/10 mm, making it significantly more flexible. This flexibility allows it to withstand moderate temperature variations and adapt to environmental changes. Its ability to expand and contract under shifting conditions makes it particularly well-suited for roofing, road paving, and waterproofing applications, where materials must endure both thermal expansion and mechanical pressure. Additionally, its elasticity enhances resistance to cracking and softening due to temperature fluctuations, ensuring long-term performance in demanding environments.
Operating temperature
Bitumen 115/15:
Goes well in warmer temperatures due to its softer point
Ideal for industrial coating, road construction, and applications with full sun or hot weather exposure
Blown Asphalt 85/25:
Less soft and more flexible
Ideal for applications requiring more adhesion and flexibility to counteract movement and temperature changes
Most commonly used for sealants, pipe coating, and asphalt coating in moderate to cold climates
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.
