Asphalt modified headers are applied in asphalt or bitumen modification processes by integrating additives that enhance the material’s properties. These headers, often composed of polymers or other modifiers, are mixed with the base asphalt at high temperatures. This process improves the asphalt’s elasticity, durability, and resistance to deformation. The modified asphalt is then used in various applications, such as road construction and maintenance, ensuring better performance under varying environmental conditions.
