Performance Grade (PG) bitumen is bitumen which is graded based on its performance at different temperatures. The LTPP has given certain algorithm to calculate the temperature of the pavement based on the temperature of the air above. From this, the highest and the lowest temperatures of the pavement is calculated and the bitumen that performs well in that temperature range is selected.
