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 & consistency of bituminous materials which leads to the classification of bitumen in a range of grades from 30-120.
Viscosity Grade Bitumen
Viscosity Grade bitumen is manufactured and graded differently from other types of bitumen. This grade of bitumen has been introduced to the industry in order to make the behaviour of bitumen more predictable at various temperatures, particularly higher ones.
