Product Introduction
Viscosity Grade Bitumens are classified based on the flow behavior and viscosity of bitumen at specified temperatures. This grading system provides a more direct evaluation of bitumen flow characteristics under defined temperature conditions.
Key Features
Classification based on viscosity
Viscosity control at 60°C and 135°C
Ability to select the appropriate grade according to production and service conditions
Advantages
Better control of bitumen flow behavior compared with Penetration Grade Bitumen
Helps determine appropriate mixing and processing temperatures
Availability of different grades for various climatic and traffic conditions
Applications
Production of Hot Mix Asphalt (HMA)
Road and highway paving
Road construction projects under various climatic conditions
