A Versatile Binder for Road Construction
What is VG30 Bitumen?
VG30 bitumen, or Viscosity Grade 30 bitumen, is a type of asphalt binder commonly used in road construction and maintenance. It is a petroleum-based product derived from crude oil and refined to achieve specific viscosity characteristics. The “VG” designation indicates that its properties are classified based on its viscosity, which is a measure of its resistance to flow.
