GTA modified bitumen enhances performance in modified asphalt applications by improving elasticity, temperature resistance, and adhesion properties. The incorporation of GTA increases the binder’s resistance to deformation and fatigue, leading to longer-lasting pavement. Additionally, it enhances the material’s resistance to aging and oxidative degradation, ensuring better durability under varying environmental conditions. Overall, GTA modified bitumen contributes to superior performance characteristics, making it ideal for high-stress applications in road construction.
