General Description of Blown Asphalt 75/35

Oxidized Bitumen 75/35 is a type of bitumen or asphalt binder commonly used in road construction and paving projects. The “75/35” designation refers to its penetration and softening point properties.

Here’s a general description:

Blown Asphalt 75/35 is derived from the refining of crude oil and undergoes a blowing process to modify its properties. It has a penetration value of 75 dmm (deci-millimeters) at 25°C, indicating its consistency and ability to penetrate aggregate materials. The softening point of 35°C signifies its temperature susceptibility, determining its performance under various climatic conditions.

This specific type of asphalt binder is known for its medium penetration and relatively low softening point, making it suitable for moderate to high-temperature regions where flexibility and resistance to deformation are crucial. It provides good adhesion to aggregates, ensuring durable and long-lasting road surfaces. Additionally, Blown Asphalt 75/35 may be modified further with additives to enhance its properties for specific applications, such as improved aging resistance or increased elasticity.

The difference between Oxidized bitumen 90/15 and Oxidized bitumen 75/35

The main differences between Oxidized Bitumen 90/15 and Oxidized Bitumen 75/35 lie in their penetration values and softening points, which affect their performance and suitability for various applications. Here’s a breakdown of the differences:

1. Penetration Value:
   – Oxidized Bitumen 90/15 has a higher penetration value of 90 dmm (deci-millimeters) at 25°C compared to Oxidized Bitumen 75/35, which has a penetration value of 75 dmm at the same temperature.
   – The higher penetration value of Oxidized Bitumen 90/15 indicates that it is softer and more fluid at room temperature, allowing it to penetrate aggregate materials more easily.
2. Softening Point:
   – Oxidized Bitumen 90/15 has a lower softening point of 15°C compared to the softening point of 35°C for Oxidized Bitumen 75/35.
   – The lower softening point of Oxidized Bitumen 90/15 means that it becomes softer at lower temperatures, making it more suitable for applications where flexibility and deformation resistance are critical, especially in colder climates.
3. Applications:
   – Due to its higher penetration and lower softening point, Oxidized Bitumen 90/15 is commonly used in applications where greater flexibility and adherence to substrates are required, such as waterproofing membranes, joint fillers, and crack sealants.
   – Oxidized Bitumen 75/35, with its lower penetration and higher softening point, is suitable for applications where stability at elevated temperatures and resistance to deformation are essential, such as road construction, roofing materials, and pavement sealing.
4. Climate Considerations:
   – The choice between Oxidized Bitumen 90/15 and Oxidized Bitumen 75/35 may also depend on the climate conditions of the region where the product will be used. For example, Oxidized Bitumen 90/15 may be preferred in colder climates, while Oxidized Bitumen 75/35 may be more suitable for hotter climates.

In summary, while both Oxidized Bitumen 90/15 and Oxidized Bitumen 75/35 are types of oxidized bitumen used in construction and industrial applications, their differences in penetration values and softening points make them suitable for distinct purposes and environmental conditions.
