What is Oxidized Bitumen 115/15?
Polycyclic aromatic hydrocarbons and blown bitumen are two types of solid oxidized grade pure petroleum bitumen that are typically employed for various construction-related applications. 70% of our capacity is devoted to Bitumen 115/15, the most oxidized bitumen that is still viable.
The semi-solid oxidized grade of pure petroleum bitumen, known as Oxidized Bitumen 115/15, is classified as a polycyclic aromatic hydrocarbon. Oxidized bitumen is typically utilized for various applications in the construction industry. Because they have been delivering bitumen products for many years, our sales team is dedicated to knowing your needs.
Oxidized bitumen 115/15 is one of the best grades. So why?
Because, The oxidation process involves blowing air through heated bitumen, which changes its molecular structure and gives it greater mechanical qualities compared to regular penetration-grade bitumen. Because of its exceptional durability, resistance to cracking, and great flexibility, oxidized bitumen 115/15 is a highly recommended option for a variety of building applications, including waterproofing and roofing. This particular grade is very useful in temperature-variable locations since it continues to function consistently even in the most adverse circumstances.
What method tests the softening point of oxidized bitumen 115/15?
To test the softening point of blown bitumen 115/15, the Ring and Ball test is commonly used. In this process, a bitumen sample is heated, and its behavior under particular conditions is observed.
The softening point test is important because it determines how the bitumen will perform under heat stress. In hot climates or high-temperature industrial applications, this feature ensures that the material does not become excessively fluid and lose structural integrity.
Process of Oxidized Bitumen 115/15 manufacturing
Oxidized Bitumen 115/15 is created to meet tough applications such as waterproofing systems, road patching, and industrial adhesives. Its manufacturing involves controlled air-blowing that completely transforms the bitumen’s physical and chemical structure.
The process begins by heating penetration-grade bitumen to a high temperature—typically between 250°C and 300°C—to reduce its viscosity and prepare it for oxidation. Once the bitumen has been heated to the required temperature, air is introduced under pressure, which triggers a series of chemical reactions. The reactions modify the molecular makeup of the bitumen, giving it greater rigidity and resistance to heat.
Blowing rate and blowing time control precisely enables the resulting end product to comply with specific softening point, penetration, and durability requirements. The end product is a high-performance bitumen with enhanced resistance to heat, oxidation, and aging, hence qualifying for protective and durable infrastructure use.
Application of Oxidized Bitumen 115/15
Oxidized Bitumen 115/15 is a versatile material used in various industries, including waterproofing, road construction, industrial coatings, adhesive manufacturing, and packaging. Its resistance to water and moisture ensures long-lasting protection against weather conditions. In road construction, it enhances the durability of asphalt pavements by improving the binding properties of asphalt mixtures.
It is also used in industrial coatings for pipelines, metal structures, and electrical components due to its excellent adhesion, resistance to chemicals, and insulating properties. It is also used in adhesive manufacturing for its high softening point and strong binding capabilities, making it suitable for creating durable and flexible solutions. In the packaging industry, it is used for protective linings of chemical containers, making the storage and transportation of sensitive materials safe.
Storage and Handling
Blown asphalt 115/15 is best up to 10 years from the day it was manufactured. It is suggested for higher time of warehouse keeping to keep the bitumen under shelter and out of the rain and sunshine.
Furthermore some of the major advantages of this type of bitumen are that it is completely water resistant, highly flexible and durable. In addition, it is chemically very stable.
Oxidized Bitumen is very flexible compound that is not only chemically stable but also a very durable compound apart from being completely water resistant. Lastly, Oxidized Bitumen has some very prominent technical advantages that makes it a very sought after compound in various applications.
Comparison Oxidized Bitumen 115/15 and85/25
Oxidized Bitumen 115/15 and 85/25 differ mainly in penetration values and softening points, which govern their usage. Bitumen 115/15 has a significantly higher softening point and lower penetration, hence more heat-resistant and harder in consistency. This makes it ideal for hot climates, industrial grade waterproofing, and high-performance roofing.
Conversely, the low softening point and high penetration level of Bitumen 85/25 make it versatile and elastic under cold temperatures. It is more easily applied under low temperatures and hence perfect for moderate weatherproofing, pipes coating, and certain types of sealant formulation.
Even though 85/25 is better in regards to ease of use and flexibility, 115/15 is known for hardness, heat resistance, and resistance to deformation under stress. Both types have specific roles depending on climatic and structural requirement in construction and industry use.
Packing
The bitumen 115/15 is available in bulk, drum, meltable and craft bag. This bitumen 115/15 are generally shipped as a solid and heated in a kettle at the worksite.
