Troyer asphalt modification involves incorporating specific additives into the asphalt or bitumen to enhance its properties. This process typically includes blending polymers or other modifiers with the base asphalt at elevated temperatures to achieve a homogeneous mixture. The modified asphalt exhibits improved elasticity, temperature resistance, and durability, making it suitable for high-performance applications. The application can be done through various methods, including mixing in a plant or using in-line modification during production.
