FZS 2 0 modified bitumen is applied in asphalt or bitumen modification processes through a controlled blending method. Initially, the base bitumen is heated to a specific temperature, allowing for optimal viscosity. The FZS 2 0 modifier is then gradually added while continuously mixing to ensure uniform dispersion. This process enhances the bitumen’s properties, improving elasticity, temperature resistance, and durability. The modified bitumen can then be used in asphalt mixtures for road construction and maintenance, providing superior performance.
