BITUMEN
Bitumen is a binding organic material made from the by-products of refined crude oil. Bitumen is an important component of our world. The substance is responsible for waterproofing, sealing, and insulating different materials in a myriad of industries. It also is used in road construction because it is easy to produce, reusable, non-toxic, and a strong binders for production of Hot Mix Asphalt for construction of flexible pavements. Suitability of different types of VG bitumen depends on 7 day maximum air temperature of that region.

BITUMEN VG 10 OR 80/100
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.

BITUMEN VG 30 OR 60/70
This bitumen is primarily used for the construction of extra-heavy bitumen pavements that have to bear significant traffic loads. Bitumen VG30 is the most widely used type of bitumen in road construction, insulation, building construction industries, and also in the production of cutback bitumen. It’s better to know that this vg30 bitumen can be used instead of 60/70 penetration bitumen grade.
VG 30 bitumen is a popular grade of bitumen in India. Indian importers prefer this type of bitumen because its performance in Indian road construction is proved. VG 30 grade bitumen is also used for plastic roads in India. Because of having good thermal susceptibility, we use VG30 in areas that have a higher temperature. VG-30 bitumen is also suitable for use in hot and rainy weather conditions instead of bitumen penetration grades. The more viscose the bitumen, the fewer the chance of being affected by water. The difference between VG10 and VG-30 bitumen is in their viscosity level. Bitumen VG30 is more viscose than bitumen VG 10 and as a result, performs better in road construction in hot regions.

BITUMEN VG 40 OR 30/40
VG40 bitumen is used in areas in which high pressure comes from heavy traffic loads, such as intersections, near tolls booths, and truck parking lots. Due to the high viscosity of this bitumen, it is more appropriate for improving resistance to shoving and other problems associated with higher temperatures and heavy traffic loads. It’s long time that industries use vg-40 instead of the penetration grade bitumen 40/50. The Advantages in the Application of Viscosity Grade 40 Bitumen is It suitable for a temperature above 40 â—¦C , It is a preferred type of bitumen when heavy traffic load is expected. The difference between vg30 and vg40 is that the vg 30 bitumen is suitable for mild weather and vg 40 bitumen is better to use in hot climate.
