PERFORMANCE GRADE

The performance grade of bitumen or PG is the latest standard of the world.
This method is a relatively new method that classifies bitumen based on the temperature conditions of different regions.
In this method, the mechanical properties of bitumen are examined from completely scientific methods. In this method, a temperature range is assigned to the bitumen, and the consumer can choose the appropriate bitumen according to his desired location.
Today, for polymer modified bitumen and pure bitumen according to the standard, a performance grade or PG is defined according to temperature and environmental conditions. The wider range or range of PG of a compound means more desirable properties and higher resistance.
