Bernet Bitumen manufactures a full range of Performance Grade (PG) Bitumen designed and tested under the AASHTO M320 and M332 Superpave system.These high-performance binders are engineered to deliver predictable rheological behavior, long-lasting durability, and temperature-specific performance for roadways, airports, and industrial pavements worldwide.Performance Grade Bitumen represents the most advanced generation of asphalt binders, replacing traditional penetration or viscosity classifications with a climate-based, performance-driven system.
Engineered for Climate-Specific ReliabilityUnlike conventional bitumen grades, PG binders are classified according to the highest and lowest pavement temperatures at which they maintain performance integrity:

The first number (e.g., 64 in PG 64-22) indicates resistance to rutting at high temperatures, andThe second number (e.g., –22) indicates flexibility and resistance to cracking at low temperatures.This ensures that every grade performs optimally under local climatic and traffic conditions, providing longer service life and lower maintenance costs.
