Penetration Grade Bitumen
Penetration grade bitumen is unique for road construction in various environmental conditions. These grades of bitumen are named due to their level of hardness and consistency, which leads to the classification of bitumen in a range of grades from 30 to 220. The main goal for grading bitumen based on penetration is to determine their suitability for use in various construction methods and under different climatic conditions
Viscosity Grade Bitumen
Viscosity test on bitumen results the classification of bitumen in a range of grades, including VG10 Bitumen, VG20 Bitumen, VG30 Bitumen, and VG40 Bitumen. The higher the number, the harder the bitumen in the viscosity grading system. Generally, each of these viscosity grade bitumen has different application according to the two important factors such as climate and traffic conditions. The important use of VG bitumen is due to the existence of two important properties of this material which are water impermeability and high adhesion
