Blown Bitumen 105/15

Description of Blown Bitumen 105/15

Oxidized Bitumen grades are blown or oxidized bitumen ‘s 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 bitumens and a variety of uses in industrial applications.

Blown Bitumen 105/15 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.

Blown Bitumen 105/15 is based on petroleum bitumen which is made by blowing bitumen 60/70 by very hot air.

As said before, Blown Bitumen 105/15 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 IP49 or ASTM- D5.

Technical Advantages of Blown Bitumen 105/15

  • Durability
  • Flexibility
  • Water Resistant
  • Chemical Stability

Application of Blown Bitumen 105/15

Blown Grade Bitumen shall be broken up into small pieces and heated slowly to the application temperature of 220ºC to 230ºC.

Blown Bitumen should be heated double temperature against the softening point to be able to have flow and viscosity. Blown Bitumen also is the aesthetic adhesive substrate for asphalt membranes. In addition metal and concrete protective coating under atmospheric conditions. Blown Bitumen 105-15 is used for coating of pipelines. Also impregnated of the coating of papers and boards. Bonding agent for tiles and mastic also bonding agent for cork plates and adhesive for roofing felts. Furthermore, Blown bitumen is adhesive for laminated boards for protection for electrical wires.

Hard grades Bitumen is also suitable for sealing saw cuts and joints where there is expected to be the minimum amount of moving in the joint. Their wide temperature range prevents bleeding in high-temperature uses. Oxidized asphalt can also be used in industrial usages like roofing, flooring, mastics, pipe coatings, electrical roles.

Packing of Blown Bitumen 105/15

RAHA GROUP is the manufacturer of Blown Bitumen 105/15 in various packing, including bitumen 105/15 is available in 20 & 50 Kg Kraft Paper Bags / Poly Amide Bags, 25 Kg Carton box & 150, 180, 200kg Steel Drums. In addition, oxidized bitumen packing also palletize, 40 bags can stack on the pallet. 20 pallet can load to the 20ft container.

Storage and Handling

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 RAHA 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 105/15 to avoid over heating
