DESCRIPTION OF OXIDIZED BITUMEN 150/5
Oxidized Bitumen 150/5 (also known as Blown Bitumen 150/5) which goes by the name R150/5 and has a high needle penetration and a high softening point (equivalent to 150), is also known as R150/5 (equal to 5 desi-millimeter). According to this information, Blown Bitumen 150/5 is one of the extremely hard grades of the Oxidized category. It is made by combining very hot air with pure Bitumen Penetration 60/70 as input for a reactor. This results in the production of a very hard grade. R150/5 was accomplished by directing very hot air through unadulterated bitumen in an environment where the temperature and pressure were strictly controlled. It is an international testing procedure, and its datasheet is based on standards established by the ASTM. ASTM D36 and ASTM D5 are the standards that are used to determine the softening point and the penetration degree, respectively, according to the standard that was specified.
Oxidized Bitumen 150/5 is the semi-solid oxidized grade of pure petroleum bitumen categorized in polycyclic aromatic hydrocarbons and is normally used for different purposes in the construction business. 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 and is normally used for different purposes in the construction industries. Oxidized Bitumen 150/5 should be heated at 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. Oxidized bitumen 150/5 can be supplied in any grade and is 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 millimeters produced in compliance and conformity with ASTM standards.

OXIDIZED BITUMEN 150/5 USING WAY
For using Blown bitumen 150/5 first it must heat to about 300 °C for melting and using in different industries because it is hard bitumen and breakable. Oxidized Bitumen 150/5, also known as blown or air-blown bitumen, is a type of bitumen that has been subjected to an oxidation process. This process increases its softening point and enhances its properties.
HERE ARE SOME COMMON WAYS IN WHICH OXIDIZED BITUMEN 150/5 IS USED:
- Roofing and Waterproofing: One of the primary applications of Oxidized Bitumen 150/5 is in roofing and waterproofing. It is used in the manufacture of roofing membranes, roofing felts, and waterproofing materials. The oxidized bitumen forms a durable and weather-resistant layer, providing protection against moisture.
- Asphalt Pavement Construction: Oxidized bitumen is sometimes used in asphalt mixes for road construction. It can contribute to the durability and stability of asphalt pavements. However, the specific grade and application may vary based on regional specifications.
- Pipe Coating: In the oil and gas industry, Oxidized Bitumen 150/5 is used as a coating for pipes. The oxidized bitumen provides corrosion resistance and insulation to protect pipes from environmental factors.
- Joint Fillers: Oxidized bitumen is used as a component in joint fillers for construction purposes. It helps seal joints and gaps in structures, providing flexibility and preventing water penetration.
- Soundproofing Applications: Oxidized bitumen may be used in soundproofing materials for buildings and infrastructure. Its ability to absorb sound contributes to reducing noise transmission.
- Adhesives and Sealants: Oxidized Bitumen 150/5 is employed in the manufacturing of adhesives and sealants. It acts as a binder, providing adhesion and sealing properties in various industrial applications.
- Paints and Coatings: Some formulations of paints and coatings may include oxidized bitumen to enhance their properties, such as weather resistance and durability.

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 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 OIL 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 OF OXIDIZED BITUMEN 150/5
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 oxidized Bitumen 150/5 to avoid over heating.
