PG (Performance Grade) and VG (Viscosity Grade) bitumens are a new generation of refinery bitumens, classified based on performance under different temperature conditions and viscosity at high temperatures. These bitumens are widely used in modern civil engineering and road construction projects due to their thermal stability, high adhesion, and resistance to thermal cracking and permanent deformation.
