Oxidized Bitumen 105/15 is also known as Blown Bitumen 105/15 (R105/15), is a hard grade of this bitumen category. R105/15 has a lower needle penetration than R105/35. Penetration Bitumen 60/70 is a raw material and the base of other bituminous products like Blown Bitumen 105/15.
Oxidized Bitumen 105/15 is produced by aeration of pure Penetration Bitumen 60/70. The pure bitumen is exposed to very hot air under special temperature and pressure conditions that are completely controlled to obtain the product with the required characteristics. Blown Bitumen 105/15 is classified by two numbers which are softening point and needle penetration degree. These parameters are measured with international test methods of ASTM .
Blown Bitumen 105/15 has softening point and needle penetration equal to 105 And 15 desi-millimeter, respectively. Based on standard and international test methods, softening point is measured by ASTM D36, and ASTM D5 measures penetration degree.
Oxidized Bitumen 105/15 is used in numerous industrial applications like the production of special paints, civil engineering, building and road construction, for roofing, coating, flooring, as an anti-slip layer component, undercarriage sealant in the cars in the automotive industry, in the piling industry, electrical operations, for cable coating, oil and gas pipelines coating, crack sealing, in the road repair operations, for the production of pulp papers, bituminous products and textile, as a joint filling compound and sound-reducing agent, for dust proofing, waterproofing, the production of roofing felts, lacquers, varnishes, pavements and as a fuel component.
Also, Oxidized Bitumen 105/15 is used in the production of adhesives, insulation materials, bitumen membrane isolation sheets, in the chemical industry, for the production of special bitumen-based paints and pigments to protect metal structures from corrosion, and in hydraulic applications and operations. It’s used as an additive in Portland cement pavements, as a base for synthetic turf, and for rubber and plastic production.
Heating bitumen for the most final uses is a critical stage. Generally, the most important aspect in this procedure is heat control. Temperature and heat control can affect various characteristics of the product, including its quality. The safe and recommended maximum temperature is 230℃.
All oxidized bitumen is risk-free at below 100℃ during shipping operations. Heating and heat transfer should be controlled. Improper heat transfer may cause overheating and release low flash vapors and these unwanted side products have a higher fire risk.
Also, melted bitumen should not be left in the boiler to cool down. Because it can cause overheating and requires more positional energy. Furthermore, proper placement and installing of the temperature and pressure monitoring and control devices is very important. Because if their placement is not right, thermometers can’t display the real temperature, which can lead to poor monitoring and thermal conductivity.
Everyone who works in oxidized bitumen plants should wear gloves, special protective masks and safety glasses. For more information, please refer to MSDS.
