About Bitumen VG-30 (60/70) IOCL/BPCL/HPCL
Bitumen VG-30 (60/70 penetration grade equivalent) is a viscosity-grade paving bitumen manufactured by major Indian oil companies such as Indian Oil Corporation, Bharat Petroleum, and Hindustan Petroleum.
It is produced from the fractional distillation of crude oil, resulting in a black, viscous, thermoplastic material with excellent adhesive and waterproofing properties.
VG-30 is designed for heavy-duty road construction, especially in regions with high traffic load and warm climates. It serves as a modern replacement for the traditional 60/70 penetration grade bitumen under IS 73:2013 standards.

FAQ's of Bitumen VG-30 (60/70) IOCL/BPCL/HPCL:
Q: How is Bitumen VG-30 (60/70) used in road construction projects?
A: Bitumen VG-30 (60/70) is primarily applied as a binder in asphalt concrete for constructing roads and highways. Its optimized viscosity allows it to provide excellent cohesion and durability, particularly under heavy traffic and varying temperatures.
Q: What makes oxidized Bitumen VG-30 suitable for Indian weather conditions?
A: The VG-30 grade, with its 47C softening point, offers enhanced resistance to deformation and bleeding under high temperatures, making it highly effective for India's hot climate. Its oxidation process improves longevity and performance in demanding environments.
Q: Where can I purchase Bitumen VG-30 (60/70) barrels or bulk in India?
A: This grade of bitumen is widely available from authorized distributors, manufacturers, suppliers, and traders throughout India, with major brands including IOCL, BPCL, and HPCL. You can acquire it in barrel or bulk packaging as required.
Q: What is the benefit of using VG-30 over other bitumen grades?
A: VG-30 offers superior strength, flexibility, and weather resistance, making it ideal for heavy-duty projects such as highways and urban roadways. Its properties reduce maintenance needs and ensure a longer lifespan for asphalt surfaces.
Q: How is oxidized bitumen different from regular straight-run bitumen?
A: Oxidized bitumen is produced by blowing air through the bitumen, increasing its softening point and elasticity. This process makes it more resistant to softening under heat, ideal for demanding construction applications compared to conventional grades.
Q: When is the best season to utilize VG-30 bitumen for asphalt paving?
A: VG-30 can be used year-round, but it is especially effective during warm and transitional seasons due to its temperature-resistant properties, ensuring optimal workability and setting during application.
Q: What packaging sizes are available for Bitumen VG-30, and how does packaging affect its storage?
A: Bitumen VG-30 is supplied in both barrels and bulk, allowing for flexible storage and transport. Barrels are convenient for smaller projects or limited storage space, while bulk packaging is preferred for large-scale operations.
