Description
Performance Grade Bitumen PG 64-22 is a functional bitumen. this bitumen, which is graded based on its performance at different temperatures, is classified and used based on two factors, traffic and pavement temperature.
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.
Application of Performance Grade Bitumen PG 64-22
- Hot Mix Asphalt (HMA)
- spray applications for bridge deck
- pavement protective membrane with fabrics
- sealing of edges of new to old paving and crack sealing
- paving for both new construction and pavement rehabilitation
- used in temperate regions with very cold winters
