Intro

Oxidized Bitumen 90/15 is an Oxidized Bitumen produced by oxidizing selected petroleum asphalts without adding the catalyst. Oxidized Bitumen 90/15 has a high softening point, a high flash point and it is highly stable during melting. Oxidized Asphalt 90/15 is produced by the air-blowing of penetration-grade bitumen. This is done at high temperatures, resulting in a material of a much higher penetration index.

Description of Oxidized Bitumen 90/15

Oxidized Bitumen 90/15 is based on petroleum bitumen which is made by blowing bitumen 60/70 by very hot air. The designation of the Oxidized Asphalt 90/15 refers to the midpoint of the softening point acceptance criteria.

Oxidized Asphalt is a solid or semi-black solid material and gradually liquid when heated. Oxidized Bitumen grades are blown or oxidized Asphalt which are produced by passing air through soft bitumen under controlled temperature conditions. This process gives the bitumen more rubbery properties than penetration or hard grade bitumen and a variety of uses in industrial applications.

Oxidized Bitumen 90/15 is produced by either Continuous or Staggered Blowing Process. Heated Penetration Grade Bitumen under controlled environment is blown with air which controls the Oil Content in the Bitumen while it oxidized. The different grades for suited applications produced are designated by two numbers to indicate the mid-points of their softening point and penetration ranges.

Oxidized Bitumen 90/15 is based on petroleum bitumen which is made by blowing bitumen 60/70 by very hot air. In addition, the numbers relate to the midpoint of the material’s softening point and penetration respectively.
The softening point value measured by Ring and Ball method as determined by ASTM D36. Also, the penetration value is in 1/10 mm as determined by IP 49 or ASTM- D5.

Production Process of  Oxidized Bitumen 90/15

Here is a step-by-step breakdown of the production process:

• Preparation: The initial bitumen (usually penetration-grade bitumen) is prepared and heated to a specific temperature, generally around 240-270°C. This temperature must be regulated carefully to prevent the formation of unwanted by-products.
• Air Blowing: Air is introduced to the heated bitumen under pressure in a process known as air blowing. This phase is carried out in a specially designed reactor, the bitumen blowing unit (BBU).
• Chemical Reactions: The introduction of air initiates a series of complex chemical reactions. These include oxidation and polymerization, which lead to an increase in the bitumen’s molecular weight and viscosity.
• Cooling and Storage: Once the bitumen reaches the desired softening point and penetration levels, the air blowing process is stopped. The oxidized bitumen is then cooled and stored appropriately for further use or distribution.
• Quality Control: Stringent quality control measures are followed throughout the process to ensure the final product meets the necessary industry standards. Tests are performed to confirm parameters like softening point, penetration, ductility, and specific gravity.
