Oxidized Bitumen 90-10

Oxidized Bitumen 90-10 is made by ongoing or Staggered Blowing Process.
Heated Penetration bitumen under controlled environment is blown with air which controls oil content in 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.
In addition vapour of oxidized bitumen or mist can cause headache, nausea, irritation of nose and lungs. Oxidized bitumen eye contact can cause slight irritation. Also its prolonged or continual skin contact can reasons slight skin irritation. In addition, oxidized bitumen can cause thermal burns which may finish in permanent skin injury. Furthermore hot product may cause severe eye burns and/or vision defect. oxidized bitumen is not classified as-dangerous for the atmosphere. Also as inflammable.
Contact of hot material with water will finish in vio-Lententide growth and splashing or boil-over may occur.

Application of Blown Bitumen 90/10:

Technical Advantages of Blown Bitumen 90/10:

• Durability
• Flexibility
• Water Resistant
• Chemical Stability

Compared to paving grade bitumen:

• Reduced temperature susceptibility
• Exhibits a more ‘solid’ nature at ambient temperatures
• High penetration index

Handling / Storage: 

Heating of packaged bitumen is a critical phase in most of the final uses. Typically, the packaged material is heated and melted in boilers out on site.
However, control at the heating phase is very important in terms of health and safety as well as in maintaining the quality of the product.

Note must be taken of the maximum safe handling temperature of 230 C and this should not be abused. Bitumen is a poor conductor of heat, consequently, control of the heating phase is of paramount importance.

The Blown Bitumen material should be broken up prior to placement in the boiler. This exposes a larger surface area to the heat and encourages a more even heating regime. Without the larger exposed surface area, aggressive heating at the base and sides of the boiler may well result in localized overheating, altering the characteristics of the Chemical Mine World modified bitumen and potentially causing thermal cracking of the bitumen, creating the release of low lash vapors.
The flash point of the oxidized bitumen then becomes irrelevant; as these low flash vapors determine the fire risk.
Melted bitumen should not be left in the boiler and reheated from cold, as there is then a high potential for localized overheating around the heating area (lack of convection means poor heat transfer) and potential development of a pressurized pocket of low flash vapors.
Be aware of the placement of any temperature monitoring or control devices. As a result of the poor thermal conductivity of the bitumen, a thermometer in the bitumen some distance from the heat source could read significantly different (even hundreds of degrees) from the true temperature of the bitumen near the heat source.
For Health and Safety information, please make reference to the relevant MSDS.


Health & Safety:

Workers should wear protective masks, gloves, and goggles during application. The asphalt can be removed from equipment and tools with kerosene or gasoline. Care should be taken when heating Blown Bitumen 90/10 to avoid over heating.

Oxidized Bitumen 85/40

Oxidized Bitumen 85/40 or Blown bitumen is produced by blowing hot air into the penetration bitumen. This action makes the bitumen more rubbery than its original formula and it becomes harder bitumen. This bitumen recovery the weight loss under heating. Due to low thermal sensitivity, the softening point is much higher than regular bitumen and the penetration index (PI) is higher than road construction bitumen (8>PI>2) due to the letter has a gel-like structure because of asphalt accumulation.
Oxidized bitumen 85/40 is a special and most usable grade in Scandinavia.Oxidized Bitumen 85/40 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.
Chemical Mine World Oxidized Bitumen 85/40 is based on petroleum bitumen which is made by blowing bitumen 60/70 by very hot air.
The designation of the Oxidized Bitumen 85/40 refers to the midpoint of the softening point acceptance criteria.

Chemical Mine World Oxidized Bitumen 85/40 is produced by either Continuous or Staggered Blowing Process.
