This bitumen is primarily used for the construction of extra-heavy bitumen pavements that have to bear significant traffic loads.

Bitumen VG30 is the most widely used type of bitumen in road construction, insulation, building construction industries, and also in the production of cutback bitumen.

VG 30 bitumen is a popular grade of bitumen in India.

Indian importers prefer this type of bitumen because its performance in Indian road construction is proved.

VG 30 grade bitumen is also used for plastic roads in India.

Because of having good thermal susceptibility, we use VG30 in areas that have a higher temperature.

VG-30 bitumen is also suitable for use in hot and rainy weather conditions instead of bitumen penetration grades.

The more viscose the bitumen, the fewer the chance of being affected by water.

30 In VG 30 bitumen means the range of viscosity [(100 +- 20) * 30] in terms of Poise.

For VG 30 grade bitumen, the minimum viscosity at 60°c is calculated like this: 80 * 30 = 2400 Poise.

The maximum viscosity is also calculated by this formula 120 * 30 = 3600 poise.

The difference between VG10 and VG-30 bitumen is in their viscosity level.

Bitumen VG30 is more viscose than bitumen VG 10 and as a result, performs better in road construction in hot regions.


It is suitable for temperature above 300C,

For a clayed soil, bitumen with higher viscosity is more suitable,

VG30 is more suitable for road construction in a rainy weather.
