Considered as the most reliable & versatile material that stands the test of time & weather, Bitumen is used for construction of roads & airfields, damp-proofing, roofing, pool lining, pipe coating, & even sound proofing. The company has made its mark as an eminent supplier of Bitumen. Due to unmitigated engineering & stringent parameters, we render a product that has impeccable quality.
| Sr No. | GRADES | APPLICATIONS |
|---|---|---|
| 1 | VG-10 | Paving & surface dressing in very cold climate Manufacturing of bitumen emulsion & modified bitumen products. |
| 2 | VG-20 | Paving in cold & high altitude areas |
| 3 | VG-30 | Construction of heavy-duty bitumen pavements with heavy traffic |
| 4 | VG-40 | For stressed areas like toll booth, intersection, truck parking area, etc. |
VG-10 BITUMEN : VG-10 is widely used in spraying applications such as surface-dressing and paving in very cold climate in lieu of old 80/100 Penetration grade. It is also used to manufacture Bitumen Emulsion and Modified Bitumen products.
VG-30 BITUMEN : VG-30 is primarily used to construct extra heavy duty Bitumen pavements that need to endure substantial traffic loads. It can be used in lieu of 60/70 Penetration grade.
VG-40 BITUMEN : VG-40 is used in highly stressed areas such as intersections, near toll booths and truck parking lots in lieu of old 30/40 Penetrati on grade. Due to its higher viscosity, stiffer Bitumen mixes can be produced to improve resistance to shoving and other problems associated with higher temperature and heavy traffic loads.
