VG 30 bitumen
This bitumen is used primarily to construct heavy-duty bitumen pavements that are expected to support significant traffic loads. In the road construction industry, in the insulation industry, in the construction of buildings, and in the production of cutback bitumen, bitumen VG30 is the most widely used type. Vg30 bitumen can be used as an alternative to penetration bitumen 60/70.

Market for VG 30 bitumen
The Indian market is a big market for VG 30 bitumen. This type of bitumen is preferred by Indian importers because it has proven performance in road construction in India. As a result of its high thermal resistance, VG30 is used where temperatures are high. As an alternative to bitumen penetration grades, VG-30 bitumen is also suitable in hot and rainy weather conditions. The more viscous the bitumen, the lower the chance of being contaminated by water.
