Oxidized Bitumen 105/15 Description
Oxidized asphalt 105/15 (another word, blown asphalt 105/15, oxidized bitumen 105/15) is Semi Solid grade of pure petroleum bitumen manufactured by air-blowing through an asphalt flux. Special physical properties of its grade can be used in different applications in the construction business. Oxidized asphalt 105/15 is based on petroleum bitumen which is made by blowing bitumen 60/70 by very hot air. The numbers relate to the midpoint of the material’s softening point and penetration respectively. The softening point value is the degrees Centigrade measured by the Ring and Ball method as determined by ASTM D36. The penetration value is in 1/10 mm as determined by IP49 or ASTM- D5.
Oxidized Bitumen 105/15 Applications
Oxidized asphalt 105/15 uses in the chemical, fuel, paints, lacquers, varnishes, paper-pulp-board, textile processing, road construction, pavement, crack seal and repairmen, civil works, roofing, construction industries; sealing and insulating buildings, adhesive, construction materials additive, dust-binding, insulating and impregnating agent, make rubber and plastic products. The oxidized asphalt 105/15 products are for paving. also used in asphalt-based paints for corrosion protection of metals, inlining public works structures, adhesives in electrical laminates, a base for synthetic turf; typical uses for asphalt 105/15 used also for water-proof application and corrosion resistance for pipe coating, Portland cement pavement, hydraulic applications, paint manufacturing, caulking, mastics, and damp proofing. Asphalt 105/15 is using the insulation and isolation bitumen membrane sheet. The car undercoating Automobile industry is especially required for Blown Asphalt. Vehicle undercoating material is based on Bitumen. Bitumen provides excellent waterproof, dustproof, and noise proof for automobile undercoating. The oxidized asphalt 105/15 should be heated double temperature against the softening point to support have flow and viscosity. To use asphalt 105/15, surfaces must be dry, clean and after loose particles, formwork, curing products, irregularities, slurry, etc.

Storage and Handling
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.
The 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 before 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.
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 overheating.
