Oxidized Bitumen Grade 95/25
What is Oxidized Bitumen Grade 95/25?
Oxidized Bitumen Grade 95/25 is a type of bitumen that is produced by blowing air through hot bitumen under controlled temperature conditions. This process oxidizes the bitumen and increases its softening point, making it more durable and suitable for high-temperature applications.
The "95/25" designation in the name refers to the softening point and penetration of the bitumen. In this case, the softening point of the bitumen is 95°C, while the penetration is 25 dmm (decimillimeters).
Oxidized Bitumen Grade 95/25 is a highly viscous and stiff material, making it ideal for use in roofing and waterproofing applications. It is also used in the production of pavement sealants, adhesives, and electrical products. Like other grades of oxidized bitumen, its properties can vary depending on the manufacturer and production process. Therefore, it is always best to check the specifications provided by the supplier or manufacturer before purchasing the product.
Oxidized Bitumen Grade 95/25 is a type of bitumen that is produced by oxidizing bitumen to increase its softening point and improve its durability. The "95/25" in its name refers to its softening point and penetration value, respectively.
The softening point of Oxidized Bitumen Grade 95/25 is typically between 90 and 100°C, which is higher than that of other bitumen grades. The penetration value is typically between 20 and 30 dmm, which is lower than that of other bitumen grades. This combination of high softening point and low penetration value makes Oxidized Bitumen Grade 95/25 ideal for use in hot climates where high temperatures can cause other bitumen grades to soften and deform.
This grade of bitumen is more brittle and hard than the penetration grade bitumen, and it is commonly used in roofing applications, such as for the production of asphalt shingles, as well as for waterproofing and sealing surfaces. It also used as a waterproofing membrane, insulation material, and in the production of industrial and construction adhesives.
Oxidized bitumen is also used in the production of bitumen emulsions, which are suspensions of bitumen droplets in water. These emulsions are used in various construction applications such as paving, road stabilization, and soil stabilization.
It's important to note that Oxidized Bitumen Grade 95/25 has a higher penetration value than other oxidized bitumen grades, such as 115/15 and 150/5, which means it is softer and more flexible. As a result, it is generally used in applications where a higher degree of flexibility is required.

History of Oxidized Bitumen Grade 95/25
The history of oxidized bitumen dates back to the early 20th century, when it was first developed as a way to improve the durability and weather resistance of bitumen. However, the exact history of Oxidized Bitumen Grade 95/25 is not well-documented.
Oxidized Bitumen in general was first produced by the American oil and gas company, Standard Oil of Indiana, in the 1920s. The company developed a new refining process that involved blowing air through heated bitumen, which caused it to oxidize and harden. This process resulted in a bitumen product that had improved weather resistance, higher softening point, and lower penetration value compared to unmodified bitumen.
Over time, the use of oxidized bitumen became more widespread, and various grades were developed to meet different application requirements. Oxidized Bitumen Grade 95/25 is one of these grades and is specifically designed for applications that require high durability and resistance to temperature and weathering.
