Bitumen VG-10, VG-30, VG-40 and Other Grades

BitChem offers a wide variety of grades of bitumen available as per applicability.

  • VG-10 - Suitable for paving roads in a very cold climate. The air temperature that matches VG10 bitumen ranges from -100C to 250C
  • VG-30 (BIS Licence Certified) - most widely used type of bitumen in road construction, insulation, building construction industries, and also in the production of cutback bitumen. Suitable for hot regions
  • VG-40 (BIS Licence Certified) – Suitable for areas with high traffic loads and for road construction in hot weather
  • 60/70 Refinery Embossed
  • 60/70 Grade - Similar in use as VG-30
  • 80/100 Grade – Similar in use as VG-10
  • 80/100 Jey Oil Refinery Embossed

The vast majority of applications for bitumen products are in construction; one of the most useful qualities of bitumen – and the products derived from it – is as a barrier to water penetration. Around 10% of the global bitumen production goes into roofing, and another 5% goes into sealing and insulating materials such as paint, pipe coatings, and carpet tiles. There are many bitumen and bituminous products but typically they go into applications such as roofing, damp proofing, waterproofing, paints, car parks, road, runways, fence treatments, and so on. In the production of asphalt for road and highway surfacing, bitumen is used as a binder and combined with aggregates to create the top wearing surface. One of the main advantages of bituminous asphalt is that it is easily and relatively cheaply patched and repaired.
