FAQ's of Bitumen VG-10 (80/100) IOCL/BPCL/HPCL:
Q: How is Bitumen VG-10 (80/100) commonly used in construction?
A: Bitumen VG-10 (80/100) is primarily used as a binder in road construction, providing strong adhesion and flexibility to asphalt mixtures. Its properties make it ideal for highways, city roads, and even airport runways, ensuring a durable and smooth driving surface.
Q: What is the process of applying Bitumen VG-10 during road construction?
A: Bitumen VG-10 is heated to the required temperature and then blended with aggregates to form asphalt concrete. This mixture is spread, compacted, and allowed to cool, creating a tough and weather-resistant road surface.
Q: When should one choose VG-10 over other bitumen grades?
A: VG-10 is suitable for areas with moderate temperatures, as its softening point of 40C ensures it performs well without becoming too soft in the Indian climate. It is an excellent choice for surfacing new roads or maintaining existing ones in regions without extreme heat.
Q: Where can Bitumen VG-10 be sourced in India?
A: Bitumen VG-10 can be sourced from leading manufacturers and suppliers like IOCL, BPCL, HPCL, as well as reputable distributors and traders across India, ensuring nationwide availability for infrastructure projects.
Q: What are the benefits of using Bitumen VG-10 (80/100) for road construction?
A: The key benefits include improved durability, high-temperature stability, and resistance to water and deformation. These characteristics make it particularly effective for withstanding the heavy loads and fluctuating climates typical of Indian roads.
