Bitumen vg 40
Viscosity Grade Bitumen 40 Description.
Bitumen VG 40 is a type of bitumen that is commonly used in road construction and maintenance. It is a highly viscous material that is derived from crude oil. Viscosity Grade 40 Bitumen has a higher viscosity than VG-30 bitumen, which makes it more suitable for use in areas with high traffic volume and heavy vehicles.
With its viscosity range carefully calibrated to provide optimal performance, VGB 40 exhibits a viscosity of 4000 to 6000 centipoise (cP) at a temperature of 60°C (140°F). This viscosity range indicates its resistance to flow at higher temperatures. When exposed to heat, VGB 40 maintains its consistency, effectively adhering to aggregates and forming a durable binding matrix in asphalt mixtures.
