Specification And Performance of oxidized bitumen 110/30

Oxidized Bitumen 110/30 can be made either by Continuous or Staggered Blowing Processes. When heated and oxidized under controlled conditions, penetration grade bitumen is blown with air, which controls the oil content in the bitumen. There are different grades for suitable applications, which are designated by two numbers indicating the mid-points of their softening point and penetration ranges.

Oxidized Bitumen 110/30 consists of two numbers, 110 and 30. The first is the softening point (in degrees Celsius), while the second is the penetration at 25°C (in tenths of an inch).

Bitumen 110/30 is semi-solid oxidized petroleum bitumen which belongs to polycyclic aromatic hydrocarbons and can be used for various purposes in the construction industry.

The iron content of this asphalt is ideal for use in hot melt adhesives as bonding compounds to hold preformed sheets together, and the hot air blowing of bitumen 60/70 yields the structure that is bonded with oxidized bitumen 110/30.

Uses of Oxidized Bitumen 110/30

• Oxidized bitumen 110/30 is widely used in a variety of applications, such as anti-slip layers, roofing felt, sound dampening, under carriage sealant in automobiles, electric cable joint protection, joint filler, sealant compound, etc.
• As a raw material, Bitumen is used for coating, roofing, and insulating in Isolation bitumen membrane sheets. Furthermore, oxidized bitumen 110/30 is used to process chemicals, fuels, paints, lacquers, varnishes, paper, pulp-board, and textiles. Construction includes road construction, pavement, crack repair, civil works, and roofing. Additionally, it is used for sealing and insulating buildings, adhesive, construction materials additive, dust-binding, and coating. In rubber and plastic products, it is used as an insulating and impregnating agent.
• Paving and roofing products are made from 110/30 Bitumen. It is also used in asphalt-based paints for corrosion protection of metals, to line public works structures, in electrical laminates, and as a base for synthetic turf. Oxidized Bitumen 110/30 is also commonly used for roofing, pipe coating, Portland cement pavement, hydraulic applications, and paint manufacturing.

Asphalt Contents

Asphalt's bitumen content is one of its most important characteristics. By using a low oxidized bitumen content, you may end up with a dry, stiff mixture that is difficult to place and compact and is prone to cracking and other durability issues, as well as having less resistance to fatigue cracks. In terms of performance, too much bitumen is likely to make the asphalt uneconomic because of the relatively high cost of bitumen and, in terms of bleeding, it is likely to deform the asphalt.

Storage and Handling

Heat treatment of packaged bitumen is a critical component of most final applications. A boiler is typically used to heat and melt the packaged material on the site.Controlling the heating process is crucial, both from an occupational health and safety perspective and for product quality.

You should be cautious about exceeding the maximum temperature for safe handling, which is 230°c. Bitumen is a poor conductor of heat, so control of the heating phase is necessary.Prior to placing the Oxidized Bitumen in the boiler, the material should be crushed. Thus, a larger surface area is exposed to the heat and a more even heating regime is achieved. Because of the larger exposed surface area, aggressive heating at the base and sides of the boiler may well result in localized overheating, changing the characteristics of the modified bitumen and possibly causing thermal cracking, which would lead to the release of low-lash vapors. Because the fire risk is determined by these low flash vapors, the flash point of the oxidized bitumen is no longer important.

If wet bitumen is then reheated from cold, it is more likely to overheat around the heating area due to poor thermal transfer or the development of a pressurized pocket of low flash vapors (lack of convection).

Placement of temperature monitoring or control devices should be considered. Because of the poor thermal conductivity of bitumen, a thermometer in the bitumen far from the heat source could read significantly different (by hundreds of degrees) from the true temperature of the bitumen near the heat source.
