Bitumen VG10, commonly referred to as Viscosity Grade 10 bitumen, is a unique grade of bitumen primarily used in road construction. As part of the Viscosity Grade (VG) series, VG10 is specifically designed for colder climates, ensuring optimal performance even in lower temperatures. Unlike traditional penetration grade bitumen, VG10’s classification is based on its viscosity property, which offers a more accurate measure of its performance at specific temperatures. This makes VG10 a preferred choice for regions with varying temperature ranges. Vg-10 asphalt, another name for this product, is renowned for its superior binding capabilities, making roads more durable and resistant to wear and tear. Whether you come across it as Cold climate bitumen vg10, Vg10 paving bitumen, or simply Vg-10 bitumen, you’re dealing with a product that promises quality and longevity in road construction projects.


Bitumen VG10 is a specific grade of Viscosity Grade Bitumen, a hydrocarbon material derived from the refining of crude oil. The “VG10” label indicates its viscosity level, making it particularly suited for colder climates. Unlike other bitumen grades, VG10 retains its flexibility even at lower temperatures, reducing the risk of cracks or damage to the road surface.

This grade of bitumen is characterized by its thermoplastic nature, meaning it can soften when exposed to heat and harden in cooler conditions. This adaptability ensures optimal performance across a range of temperatures, making it a preferred choice for road construction in regions experiencing colder weather conditions.

In essence, Bitumen VG 10 is a robust and adaptable road construction material, designed to offer durability and resilience, especially in challenging climatic conditions.
