Bitumen AH Grade (Aryl Hydrocarbon Bitumen), short for “Air Blown Hard” Grade bitumen, is a specific type of bitumen that finds common usage in road construction and paving projects. The “AH” designation reflects its production process, where air blowing is used to modify its properties.

Here are key attributes and applications associated with Bitumen AH Grade:

1. Higher Softening Point: Bitumen AH Grade boasts a higher softening point compared to standard bitumen. This characteristic makes it particularly suitable for regions with hot climates, where road surfaces can be exposed to high temperatures.
2. Enhanced Rut Resistance: Its elevated viscosity and hardness make Bitumen AH Grade more resistant to rutting, which refers to the formation of depressions or tracks in the pavement caused by the repeated action of wheel loads.
3. Paving and Surface Coating: Bitumen AH Grade is commonly employed in road paving projects, especially in areas with hot climates. It offers robust performance in terms of durability and resistance to high temperatures and heavy traffic.
4. Waterproofing Applications: This type of bitumen is also utilized in waterproofing applications, such as roofing and waterproof membranes. It serves to create effective barriers against moisture penetration.
5. Airfield Pavements: Bitumen AH Grade can be used in the construction of airfield pavements and runways, where it provides the required durability and can withstand the loads associated with aircraft.
6. Hot Climate Environments: Given its ability to endure high temperatures, Bitumen AH Grade is well-suited for regions characterized by extreme heat, including desert areas.

It’s important to note that specific specifications and properties of Bitumen AH Grade may vary depending on the region and manufacturer. Therefore, it is advisable to refer to the product data sheet or consult with the supplier for precise information about the characteristics and applications of Bitumen AH Grade in a particular area.
