Oxidized Bitumen 90-15
What is Oxidized Bitumen 90-15?
Oxidized Bitumen 90-15, also known as blown bitumen, is a type of bitumen produced by blowing air through hot bitumen at a controlled temperature. This process causes the bitumen to become more viscous and harder, which makes it more suitable for certain industrial applications.
Oxidized Bitumen 90-15 has a higher softening point than regular bitumen, which makes it more resistant to temperature changes and weathering. It is commonly used in the construction industry for roofing, paving, and waterproofing applications, as well as in the production of adhesives, sealants, and coatings.
The "90-15" in the name refers to the penetration and softening point of the bitumen. The penetration value is a measure of the hardness of the bitumen, and the softening point is the temperature at which the bitumen softens under specific conditions. In this case, the penetration value is 90 dmm (decimillimeters) and the softening point is 15°C.
Quality of Oxidized Bitumen 90-15
The quality of Oxidized Bitumen 90-15 can vary depending on various factors such as the raw material used, the production process, and the storage and handling conditions. However, generally, the following are some of the key quality characteristics of Oxidized Bitumen 90-15:
Softening point: The softening point of Oxidized Bitumen 90-15 is typically around 90-100°C. This indicates its ability to withstand high temperatures without melting or becoming too soft.
Penetration: The penetration value of Oxidized Bitumen 90-15 is usually around 5-15 dmm. A lower penetration value indicates a harder and more durable material.
Ductility: Oxidized Bitumen 90-15 should have good ductility, which means it can be stretched or deformed without breaking.
Solubility: The bitumen should be soluble in organic solvents such as benzene and toluene.
Color: The color of Oxidized Bitumen 90-15 is usually black or dark brown.
Stability: The material should be stable and not break down or deteriorate over time when exposed to environmental factors such as sunlight, heat, and moisture.
It is important to note that these quality characteristics may vary depending on the specific application and requirements of the end-user. It is recommended to consult with a reputable supplier or manufacturer for more specific information on the quality of Oxidized Bitumen 90-15.
History of Oxidized Bitumen 90-15
The history of Oxidized Bitumen, also known as blown bitumen, can be traced back to the early 20th century. The process of blowing air through hot bitumen to increase its viscosity and durability was first developed in the United States in the early 1900s, primarily for use in the roofing industry.
During the early years, the production of Oxidized Bitumen was done manually, where workers blew air into hot bitumen using handheld blowpipes. This was a slow and labor-intensive process that produced small quantities of bitumen.
In the 1920s, the first mechanical blowers were introduced, which made the production of Oxidized Bitumen more efficient and cost-effective. The introduction of these blowers also led to the development of new grades of Oxidized Bitumen, including the popular 90-15 grade.
Over the years, Oxidized Bitumen has become an essential material in the construction industry, particularly in the production of roofing and paving materials. It is also used in the manufacture of adhesives, sealants, and coatings.Today, the production of Oxidized Bitumen has become a highly automated process, with advanced machinery and control systems used to produce high-quality bitumen products efficiently and consistently.
