VG-30 bitumen has a higher viscosity compared to VG-10. It is a more versatile grade suitable for a wider range of applications. It is commonly used in the construction of medium-traffic roads, highways, and urban areas.

VG-30 bitumen provides a good balance of viscosity and durability for such applications. It can also be used for surface dressing, slurry seals, and as a binder for asphalt mixes.
