Description
Viscosity Grade Bitumen VG-40 is a type of bitumen used in road construction and maintenance. Viscosity grade 40 has a higher viscosity than VG-30 bitumen, which makes it more suitable for use in areas with high traffic volumes and heavy vehicles.
VGB 40 bitumen maintains its consistency when exposed to heat, bonds effectively to aggregates, and forms a durable binding matrix in asphalt mixtures.
Application of Viscosity Grade Bitumen VG-40
- Roofing
- Bridge Decks
- Waterproofing
- Hot Mix Asphalt
- Road Construction
- Pavement Rehabilitation
