Bitumen is available in several grades, each suited to different applications. The most common grades include Penetration Grade Bitumen (e.g., 30/40, 60/70, 80/100), Viscosity Grade Bitumen (VG10, VG20, VG30, VG40), and Performance Grade Bitumen (PG). Penetration grades are determined by the depth a needle penetrates the bitumen under specific conditions, indicating its hardness. Viscosity grades indicate the bitumen’s flow characteristics, while performance grades are used in regions with extreme temperatures, ensuring the bitumen performs well under specific climatic conditions.
