What is VG 30 Bitumen?
VG 30 bitumen, known for its superior properties, is primarily employed in the construction of extra-heavy bitumen pavements capable of withstanding substantial traffic loads. It stands as the most widely utilized type of bitumen in road construction, insulation, building construction industries, and the production of cutback bitumen. Importantly, VG 30 bitumen can effectively substitute the 60/70 penetration bitumen grade.
Usage of VG 30 Bitumen in India:
In India, VG 30 bitumen holds significant popularity. Indian importers prefer this bitumen grade due to its proven performance in road construction projects across the country. VG 30 grade bitumen is also a preferred choice for the construction of plastic roads in India.
Given its excellent thermal susceptibility, VG 30 bitumen is ideal for areas experiencing higher temperatures. It is equally suitable for use in regions characterized by hot and rainy weather conditions, offering advantages over conventional bitumen penetration grades. Higher viscosity in bitumen, as seen in VG 30, provides increased resistance to the detrimental effects of water.
Minimum and Maximum Viscosity of VG-30:
The “30” in VG 30 bitumen refers to its viscosity range, calculated as [(100 ± 20) * 30] in terms of Poise. The minimum viscosity at 60°C is determined using the formula: 80 * 30 = 2400 Poise, while the maximum viscosity is calculated as: 120 * 30 = 3600 Poise.
Distinguishing VG 10 from VG 30:
The primary distinction between VG 10 and VG 30 bitumen lies in their viscosity levels. VG 30 bitumen exhibits higher viscosity compared to VG 10, making it particularly suitable for road construction projects in hot regions.

Advantages of Using Viscosity Grade 30 Bitumen:
- Suitability for Elevated Temperatures: Viscosity Grade 30 bitumen is well-suited for applications in regions where temperatures frequently exceed 30°C. Its superior performance under high-temperature conditions makes it an excellent choice for road construction and related projects in such environments.
- Ideal for Clayey Soil: In areas with clayey soil, bitumen with higher viscosity, like VG 30, is preferred. The increased viscosity enhances its binding properties, ensuring better stability and durability of road surfaces in regions with clay-rich soils.
- Effective in Rainy Weather: VG 30 bitumen demonstrates superior performance in road construction projects conducted in rainy weather conditions. Its enhanced resistance to moisture ingress and cohesive properties make it a reliable choice for ensuring road integrity even during wet periods.
VG 30 Specification (ASTM):
The specifications for Viscosity Grade 30 (VG 30) bitumen, as per ASTM standards, are outlined below:
- Density: The density of VG 30 bitumen, based on ASTM standards, is approximately 1.01.

Applications of Viscosity Grade 30 Bitumen (VG-30):
- Heavy-Duty Bitumen Pavements: VG-30 bitumen finds its most common application in the construction of heavy-duty bitumen pavements that are subjected to significant traffic loads. Its high viscosity and excellent performance under elevated temperatures make it an ideal choice for such demanding projects.
- Road Construction: VG-30 bitumen is widely used in road construction projects, particularly in regions with hot and rainy weather conditions. Its superior properties, including resistance to moisture and temperature fluctuations, contribute to the longevity and durability of road surfaces.
- Waterproofing: This grade of bitumen is also employed in waterproofing applications. Its high viscosity ensures effective sealing and protection against water ingress, making it suitable for waterproofing various structures.
- Building Construction: VG-30 bitumen serves as a valuable component in building construction, particularly for roofing and sealing applications. Its ability to create strong, watertight bonds enhances the integrity of building structures.
- Cutback Bitumen Production: VG-30 bitumen is used in the production of cutback bitumen, which is a common binder for various road construction and maintenance activities.
- Replacement for 60/70 Penetration Grade: VG-30 bitumen can be used as a replacement for 60/70 penetration grade bitumen in many applications. Its improved properties offer advantages, especially in regions with challenging weather conditions.
