VISCOSITY GRADE BITUMEN
Introduction of Viscosity Grade bitumen
This particular variety of bitumen, which is of an appropriate grade, is put to use in the production of asphalt, street paving, and concrete sidewalks. Refinery bitumen is produced via vacuum baton aeration in the distillation tower. Viscosity Grade Bitumen, which is the type of bitumen that is utilized the most frequently in the manufacturing of hot asphalt, is a part of this category of bitumen. This particular variety of bitumen possesses a thermoplastic property, which is a property that causes this material to be brittle and unyielding when exposed to cold weather and to become more malleable when exposed to warm weather. Because of this quality, the combination of the viscosity of bitumen with other materials results in a road surface that is more long-lasting. As a result of the precision with which it is graded, this particular variety of bitumen is favored more than penetration bitumen.
The value of bitumen’s penetration at 25 degrees Celsius determines its classification as penetration grade, while the value of bitumen’s viscosity at 60 and 135 degrees Celsius determines its classification as viscosity grade. This demonstrates how VG bitumen is suitable for both low and high temperatures, making it possible to accurately forecast how bitumen would behave in various thermal conditions. Bitumen is divided into numerous grades after undergoing a viscosity test, including VG10 Bitumen, VG20 Bitumen, VG30 Bitumen, and VG40 Bitumen. The higher the number in the viscosity grading system, the harder the bitumen is regarded to be.
WHAT IS VISCOSITY GRADE BITUMEN?
In the production of hot asphalt for road building, viscosity bitumen is a form of bitumen that is often utilized. This form of bitumen has a thermoplastic feature that makes it bendable in warm weather and brittle and rigid in cold weather. It has a thick, gooey consistency and is quite viscous, which allows it to combine with other materials to form a durable road surface. At a refinery’s distillation tower, viscosity bitumen is created using vacuum baton aeration.

VISCOSITY GRADE BITUMEN ADVANTAGES
- In today’s world, viscosity bitumen is utilized rather than penetration bitumen since it is subjected to more stringent testing in two stages by industry professionals. First, the penetration of bitumen is tested at a temperature of 25 degrees Celsius, which is the normal temperature. However, the findings of this test are not trustworthy in the hot weather, therefore they measure the viscosity of bitumen at temperatures of 60 degrees Celsius and 135 degrees Celsius. The results of these tests show that VG bitumen can withstand temperatures in a broad range, from 25 degrees Celsius for fatigue cracking to 135 degrees Celsius for construction. Temperature susceptibility may also be established using these tests.
- Time and money may be saved because to the reduced number of tests; according to IS, it only has seven tests, while penetration has fourteen tests.
- Longer durability: the pavement made from VG Bitumen will have better performance because the viscosity value at 135°C gives a sufficient idea about mixing and compaction temperature, and as a result, pavement life is improved. This is because the viscosity value at 135°C gives a sufficient idea about mixing and compaction temperature.
- In contrast to the penetration grade, the rutting performance of any two different samples of the same VG bitumen would be quite comparable throughout the hot summer months.
- When applied at a temperature of 135 degrees Celsius, the minimum kinematic viscosity value that is provided helps to reduce the possibility of tender mixes occurring during construction.
- The use of VG bitumen is appropriate for locations that see significant volumes of vehicular activity.

Viscosity GRADE bitumen APPLICATIONS
Viscosity Bitumen is a grade of bitumen that is most often used as a paving grade. It is appropriate for the building of roads and is effective in providing prime qualities in asphalt pavements. petro naft provides a wide range of high-quality grades in this category, which has been listed below.
BITUMEN VG-10
Spraying VG10 bitumen, which has a permeability rating of 80/100, is the method of choice for coating surfaces and roads. This particular variety of bitumen is required for the manufacturing of emulsions bitumen and other modified bitumen products. This grade of bitumen can be a good substitute for penetrating bitumen 80/100.
Advantages of Viscosity Grade Bitumen 10
- It is appropriate for temperatures below 30 °C.
- It has an 800 absolute viscosity.
- When compared to VG30 and VG40, it has a better penetration value.
BITUMEN VG-20
Paving applications in areas with low temperatures and high elevations.
Advantages of Viscosity Grade Bitumen 20
- High-altitude, cold climate areas employ VG-20 bitumen, a grade of viscosity bitumen. When building roads in areas where the average temperature is between 30 and 37 °C, this grade of bitumen is appropriate.
BITUMEN VG-30
VG30 grade viscosity bitumen is used to build super heavy bituminous pavements. These types of sidewalks must withstand high and significant traffic loads, so this type of grade is used more often. Road construction, construction, insulation, and liquid bitumen are the most common industries that use this type of bitumen. VG30 bitumen is very suitable for temperate climates and can be used instead of bitumen 60/70.
Advantages of Viscosity Grade Bitumen 30
- It can withstand temperatures higher than 30 °C.
- Bitumen with a greater viscosity is more suited for a clayed soil.
- In wet conditions, VG30 is better appropriate for road building.
BITUMEN VG-40
In highly stressed areas such as intersections, highways near tolls, and truck parking lots, VG 40 bitumen with a permeability of 40/50 is used instead of the old bitumen. Due to its high viscosity, this type of mixed hard bitumen is suitable for surfaces that are supposed to bear high tensile strength loads and heavy traffic loads. This type of bitumen is used at higher temperatures and on surfaces that require more resistance and it can be a suitable alternative to penetration bitumen 40/50 and penetration bitumen 30/40.
Advantages of Viscosity Grade Bitumen 40
- It can withstand temperatures exceeding 40 °C.
- It has a 3200 absolute viscosity.
- It is the ideal kind of bitumen when there will be a lot of traffic.
