Oxidized Bitumen 95/25

General Description of Oxidized Bitumen 95/25

Oxidized Bitumen 95/25 is an oxidized Asphalt produced by oxidizing a selected petroleum asphalts without adding the catalyst. RAHA BITUMEN 95/25 has high softening point, high flash point and it is highly stable during melting.

Oxidized bitumen 95/25 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.

RAHA Bitumen 95/25 is based on petroleum bitumen which is made by blowing bitumen 60/70 by very hot air. The designation of the Oxidized bitumen 95/25 refers to the midpoint of the softening point acceptance criteria.

Oxidized bitumen is a solid or semi-black solid material and gradually liquid when heated. Oxidized Bitumen grades are blown or oxidized bitumen ‘s which are produced by passing air through soft bitumen under controlled temperature conditions. This process gives the bitumen more rubbery properties than penetration or hard grade bitumen’s and a variety of uses in industrial applications.

RAHA Bitumen 95/25 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, RAHA Bitumen 95/25 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 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.

Uses of Oxidized Bitumen 95/25

The uses of Oxidized Bitumen 95/25 are so broad in the areas it serves, starting from being an anti-slip layer for the piling industry, the production of roofing felts, to holding a very significant position in roofing and waterproofing sectors. It is also used in sound deadening felts, undercarriage sealants for automotive, protection of electric cable joints, filling compounds for joints, carpet backings, and corrosion protection.

Acoustic panels, chemical industries, fuel industries, and paints also use this type of bitumen. In construction, it serves in sealing saw cuts and joints with very minimal expected movement, and in bituminous marine mastic for oil and gas pipeline joints. Other applications include expansion joint sealing, crack repair, parquet floor repair, and as an adhesive for thermal insulation. It has also been applied in wet-briquette bonding and in various industries such as roofing, insulation, flooring, mastics, pipe coating, and electrical applications.

Technical Advantages of Oxidized Bitumen 95/25

• Durability
• Flexibility
• Water Resistant
• Chemical Stability

Compared to paving grade bitumen:

• Reduced temperature susceptibility
• Exhibits a more ‘solid’ nature at ambient temperatures
• High penetration index

Recommendations for Handling / Storage

Heating of packaged bitumen is a sensitive process since too high temperatures will endanger safety and lower the product quality. A safe maximum handling temperature of 230°C should not be exceeded because poor thermal conductivity provides a potential for bitumen to have localized overheating. The heat treatment will be easier if lumps of oxidized bitumen are broken into pieces before placing into the boiler; larger surface areas would be exposed to the heat. Failure to do so may result in overheating at the base and sides of the boiler, which will alter the properties of the bitumen, causing thermal cracking and emission of low-flash vapors that greatly enhance fire hazard. It is also not advisable to reheat cold melted bitumen because localized overheating and pressurized vapor pockets may occur due to poor convection. Temperature monitoring devices must be located with considerable care since readings far from the source of heat may be significantly different from the true temperature close to the source. For specific safety precautions see the appropriate Material Safety Data Sheet (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 Oxidized Bitumen 95/25 to avoid over heating

Application of Oxidized Bitumen 95/25

Oxidized Bitumen 95/25 is a dark industrial bitumen. Petroleum residue modified by the oxidation process. In addition, Oxidized Bitumen is produced by passing air through bitumen under controlled temperature state. Its stability ranges from highly viscous to solid. Blown bitumen grade has technical advantages such as durability, flexibility, water resistant and chemical stability. There is also the different grade of blown bitumen.
