BITUMEN PG 58-22

What is Performance Bitumen (PG)? Performance-graded (PG) bitumen is a type of bitumen that is graded based on its performance at different temperatures. In the super-pave grading system, binders are classified based on their performance in extreme hot and cold temperatures and are called performance-grade bitumen. Long-Term Pavement Performance (LTPP) offers a method and algorithm for calculating the temperature of the pavement based on the temperature of the air above. This relatively new approach to classifying bitumen is based on temperature variations and is a completely scientific method for studying the mechanical properties of bitumen. This method specifies a temperature range for bitumen, allowing consumers to select the required product. The highest and lowest temperatures of the pavement are estimated based on this method, and the bitumen that works effectively in that temperature range is selected.
