Oxidized Bitumen 85/25
Oxidized Bitumen 85/25 Description
Oxidized Bitumen 85/25 or Oxidized Asphalt 85/25 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 85/25 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. Bitumen 85/25 is based on petroleum bitumen which is made by blowing bitumen 60/70 by very hot air. The designation of the Oxidized Bitumen 85/25 refers to the midpoint of the softening point acceptance criteria.
Bitumen 85/25 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.
As said before, Blown Asphalt 85-25 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 the 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.

Recommendations for Handling / Storage
The 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.
A 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 Oxidized 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 modified bitumen and potentially causing thermal cracking of the bitumen, creating the release of low lash vapors. The flashpoint 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.

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.
The Oxidized Bitumen 85/25 should be heated double temperature against the softening point to be able to have flow and viscosity.
Surfaces must be dry, clean, and free of loose particles, formwork, curing products, irregularities, slurry, etc.

The 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.
A 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 Oxidized 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 flashpoint 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.

Oxidized Bitumen 150/5
Oxidized Bitumen 150/5 Description
Oxidized bitumen 150/5 is based on petroleum bitumen which is made by blowing bitumen 60/70 by hot air. This type of bitumen is hard and breakable. Oxidized bitumen 150/5 is the semi-solid oxidized grade of petroleum bitumen categorized in polycyclic aromatic hydrocarbons is normally used for different purposes in the construction industries. bitumen 150/5 should be heated double temperature (200ᵒ-300ᵒC) against the softening point to be able to have flow and viscosity. Normally heating of such hard oxidized bitumen should be arranged via hot oil by circulation inside of the isolated jacket. Bitumen oxide 150/5 from penetration grade bitumen, which is blown by hot air in a controlled process until the desired specification is reached. HJ Oil oxidized bitumen 150/5 can be supplied in any grade and are designated by two numbers to indicate the softening point and penetration ranges. The oxidized bitumen 150/5 means the softening point is 150°c and penetration is 15 desi millimeter is produced in compliance and conformity with ASTM standard.
Oxidized Bitumen 150/5 Applications
This Grade of Oxidized uses in the chemical, raw material for bitumen coat, lacquers, varnishes, paper-pulp-board, textile processing, pavement, crack seal and repairmen, civil works, bitumen coat for piping, roofing, construction industries; sealing and insulating buildings, adhesive, construction materials additive, road construction, dust-binding, insulating and impregnating agent, isolation bitumen membrane sheet, make rubber and plastic products. bitumen 150/5 products are for paving, roofing; also used in asphalt-based paints for corrosion protection of metals, inlining public works structures, adhesives in electrical laminates, the base for synthetic turf; typical uses for bitumen 150/5 include roofing, pipe coating, hydraulic applications, 150/5 is mainly using in paint manufacturing and coating in the hot area.
Before using bitumen 150/5 surfaces must be dry, clean, and free of loose particles, curing products, irregularities, and slurry. If you use this type of bitumen without cleaning the area the bitumen 150/5 will easily remove.
Blown Asphalt 150/5 Storage/handling
blown asphalt 150/5 has 10 years validity with multi-time heating and cold, please refer to MSDS. It is better to keep the bitumen 150/5 under shelter and out of the rain, the sun.
Blown Asphalt 150/5 Packing
bitumen 150/5 is available in 25 kg meltable and craft bag, drum, and bulk. Normally oxidized bitumen packing on the pallet and 40 bags can stack on the pallet. 20 pallets can load to the 20ft container.
