Product Types
Viscosity Grade 10-Viscosity Grade
This type of bitumen is utilized to stain cracked surfaces and spray various applications. It can be an alternative for the penetration grade bitumen 80-100 in very cold areas. This category of bitumen is also employed to produce emulsion and modified bitumen.
Viscosity Grade 20-Viscosity Grade
This type of bitumen is mostly used in cold climates and highlands.
Viscosity Grade 10-Viscosity Grade
Viscosity Grade 30-Viscosity Grade
This category of bitumen is used primarily for the surfaces that undergo very heavy loads and need to withstand high traffic loads. It can be used instead of bitumen grade 60-70.
Viscosity Grade 40-Viscosity Grade
This category of bitumen is used instead of penetration grade bitumen 40-30 in areas with high traffic loads and pressure such as intersections, near road tolls, and parking lots of heavy vehicles. Due to the high viscosity of this type of bitumen, it can resolve the problems of surface tension, resistance, higher temperatures, and heavy traffic loads.
