What is VG 10 bitumen?
VG10 bitumen is the softest grade of viscosity bitumen. This type of bitumen is widely used for spraying applications and surface coating.
VG 10 bitumen means that your bitumen is also suitable for paving roads in a very cold climate instead of the old 80/100 penetration grade. The air temperature that matches VG10 bitumen ranges from -100C to 250C.
Due to the high temperatures in hot climatic zones, the application of VG10 cannot provide desirable rutting resistance.
This type of bitumen is also used to manufacture bitumen emulsions and modified bitumen products especially in India.
As a viscosity grade bitumen, VG10 has a better performance in cold weather.
What are the Advantages in the Application of Viscosity Grade 10 Bitumen?
- – It is suitable for temperature under 30 ◦C
- – Its absolute viscosity is 800
- – It has a higher Penetration Value in comparison to VG30 and VG40
