Abstract: This research aims to enhance asphalt mixtures by using modified materials and optimizing the design of the asphalt surface-layer, ultimately designing an asphalt mixture suitable for practical applications under severe conditions. Although numerous studies exist on modifying and improving asphalt mixtures, research remains limited in determining the optimal ratio for the use of KUMHO KTR-103. The potential of KUMHO KTR-103 to modify basic and rheological properties of asphalt binder has been examined. The experimental results showed that adding 4% of KUMHO KTR-103 by asphalt binder weight improves asphalt binder properties while remaining within the standard limits of performance grade 76-10 asphalt binder. Asphalt mixtures designed with modified asphalt binder KUMHO KTR-103 were manufactured, and the properties of the modified asphalt mixtures were examined. The test results of the modified asphalt mixture established that adding KUMHO KTR-103 to the asphalt binder not only improved rutting resistance but also increased its toughness, potentially enhancing the asphalt mixture's performance against fatigue and low-temperature cracking. Through rigorous testing that achieved the optimal balance between the mixture's flexibility, durability, and crack resistance, the final formulation of the working mixture was determined, with observations that thermal stability was maintained under standard operating conditions to ensure outstanding performance.
