About Bitumen VG-40 (60/70) Non Embossed
Bitumen VG-40 (60/70) Non-Embossed is a high-performance viscosity-grade bitumen designed for heavy-duty road construction and infrastructure projects. It is produced from selected crude sources and processed to meet IS 73:2013 standards, ensuring consistent quality and durability.
This grade corresponds to penetration grade 60/70 in performance but offers improved viscosity control, making it suitable for extreme climatic conditions, particularly high temperatures and heavy traffic loads. The non-embossed form indicates a smooth, homogeneous material without surface patterning, ensuring uniform mixing and application.
VG-40 bitumen is widely used in highways, airport runways, industrial pavements, and high-stress areas where resistance to rutting, deformation, and thermal cracking is essential.
