Performance Grade (PG) Bitumen: The Global Standard

Performance Grade (PG) bitumen is the latest international standard for bitumen classification, designed to match the temperature conditions of different regions.

This modern classification method evaluates the mechanical properties of bitumen through scientific testing, ensuring optimal performance in specific climates. Each PG bitumen is assigned a temperature range, allowing consumers to select the most suitable grade for their location.

Currently, PG grading is applied to both polymer-modified and pure bitumen, following established standards that account for temperature variations and environmental factors. The wider the PG range, the greater the bitumen’s durability and resistance, making it more effective for high-performance applications.
