AH bitumen
AH Bitumen is a tough, high-quality material made to handle extreme heat and heavy traffic. It resists heat and rutting, making it perfect for roads, airfields, and waterproofing projects. It’s built to last, even in the hottest climates.
AH bitumen’s description
AH Bitumen (Aged Hard) is a hardened, more viscous type of viscosity grade bitumen created through an aging process that simulates natural exposure to sunlight and air. AH bitumen is produced through air blowing to modify its properties, making it ideal for paving and other infrastructure projects.
It is primarily used in road construction and asphalt paving for its durability and waterproofing properties. Additionally, bitumen serves in roofing, industrial applications like emulsion paints, and soundproofing. The quality of bitumen depends on the crude oil source and refining process.
AH bitumen’s formula
AH-bitumen is a specific grade of bitumen commonly used in paving and industrial applications. “AH” typically refers to Asphalt Hardness or Asphalt Heavy, highlighting its performance characteristics.
Key elements form the foundation of AH bitumen‘s structure, influencing its physical properties and performance in various applications. They are:
- Carbon (C): 80–88%
- Hydrogen (H): 8–12%
- Sulfur (S): 1–9%
- Oxygen (O): 0.5–2%
- Trace amounts of Nitrogen (N): 0.1–1%
AH bitumen components vary depending on the specific grades, influencing their suitability for different climates, traffic conditions, and infrastructure needs. These components are listed:
