Oxidized Bitumen 75/25 Definition

Oxidized Bitumen 75/25 refers to a specific type of bitumen or asphalt binder that has undergone an oxidation process, resulting in its distinctive properties. The numbers “75/25” represent its penetration and softening point values, which are key characteristics used to classify and specify asphalt binders.

Blown asphalt 75/25 (in another word, blown bitumen 75/25, oxidized asphalt 75/25) 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. Blown asphalt 75/25 is based on petroleum bitumen which is made by blowing asphalt 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. This product, utilized in the industrial sector, exhibits predominantly “solid” characteristics at ambient temperatures and provides SUPERIOR adhesive and waterproofing qualities when applied hot and allowed to cool than Oxidized Bitumen.
ZUMRUT KIMYA company guaranty the quality of ZUMRUT blown asphalt 75/25 with the arrangement of the international inspector to check quality and quantity of the asphalt 75/25 during the loading to the vessel and controlling the production by QC by batch test report before shipping. RABIT Company guarantees the quality to meet with ASTM.

Here’s a breakdown of what Oxidized Bitumen 75/25 typically means:

1. Penetration Value: The “75” in Oxidized Bitumen 75/25 denotes its penetration value, measured in deci-millimeters (dmm) at a standard temperature of 25°C. A penetration value of 75 indicates that the bitumen has a medium consistency, neither too hard nor too soft. It means that a standard needle penetrates the bitumen to a depth of 75 deci-millimeters under specific conditions.
2. Softening Point: The “25” in Oxidized Bitumen 75/25 represents its softening point, measured in degrees Celsius (°C). The softening point is the temperature at which the bitumen becomes soft enough to flow under the influence of a standard weight. A softening point of 25°C indicates that the bitumen exhibits relatively low temperature susceptibility and remains stable at moderate temperatures.

Recommendations for Handling / Storage Blown Asphalt 75/35

Handling and storing Blown Asphalt 75/35 requires careful consideration to ensure its quality and safety. Here are some recommendations:

1. Storage Conditions: Store Blown Asphalt 75/35 in a cool, dry, and well-ventilated area away from direct sunlight, heat sources, and ignition materials. Maintain temperatures below its softening point to prevent excessive softening or degradation.
2. Container Selection: Use appropriate containers made of materials compatible with asphalt, such as steel drums or tanks, to prevent contamination and maintain product integrity. Ensure that containers are tightly sealed to prevent moisture ingress.
3. Handling Precautions: Wear appropriate personal protective equipment (PPE), including gloves, safety goggles, and protective clothing, when handling Blown Asphalt 75/35 to prevent skin contact and inhalation of fumes. Avoid prolonged or repeated exposure to asphalt vapors.
4. Avoiding Contamination: Prevent contamination of Blown Asphalt 75/35 with water, solvents, acids, or other incompatible materials, as it can affect its properties and performance. Clean all equipment and surfaces thoroughly before and after handling the product.
5. Heating and Melting: If the asphalt needs to be heated for application, use indirect heating methods such as hot oil baths or steam jackets to avoid direct exposure to open flames or high temperatures, which can cause thermal degradation or fire hazards.
6. Mixing and Agitation: Stir or mix Blown Asphalt 75/35 thoroughly before use to ensure uniform consistency and temperature distribution. Use mechanical mixers or agitators designed for asphalt products to achieve proper blending.
7. Spill and Leak Response: Have spill containment measures in place, such as absorbent materials and spill kits, to quickly respond to accidental spills or leaks. Follow appropriate procedures for cleanup and disposal of spilled material in accordance with local regulations.
8. Transportation: When transporting Blown Asphalt 75/35, ensure compliance with transportation regulations for hazardous materials. Use suitable tanker trucks or containers equipped with proper venting and safety features to prevent leaks or spills during transit.
