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.
Properties
Softening Point: ~115°C
Penetration: 10-20 dmm
Appearance: Solid black, shiny appearance
Stability: Chemically stable, water-resistant, UV & aging-resistant
Applications
Oxidized Bitumen 115/15 has widespread uses in:
- Waterproofing basements, roofs & tunnels
- Road patching and pavement sealing
- Coating pipes and corrosion protection
- Industrial adhesives and insulation
- Packaging of chemical containers
Because of its high softening point, it is reliable in hot climates and industrial settings where heat resistance is necessary.
Manufacturing Process
Heating: Penetration-grade bitumen is heated to ~250–300°C
Blowing Air: Controlled air flow changes molecular structure
Result: Bitumen is more elastic, harder, and heat-stable
This procedure ensures conformity with the required softening point, penetration, and resistance to aging.
Softening Point Test (Ring & Ball Method)
The Ring and Ball test is used to check the temperature resistance of Bitumen 115/15. It checks the softening point — a very important factor in assessing performance when subjected to heat stress.
