Investigation shows how mechanical response influences rutting performance in asphalt pavements, indicating material selection is crucial for durability.
This study investigates the mechanical response and rutting performance of asphalt pavements using 3D-Move Analysis software based on the three-dimensional continuous finite layer method. A multivariate orthogonal experimental design was employed to simulate two pavement structures with different surface layer combinations (SBS-modified asphalt and SMA) under coupled thermal-mechanical loading. Key parameters including vehicle speed (35–77 km/h), temperature (0–40°C), and traffic volume (15,000–45,000 vehicles/day) were systematically analyzed. Results demonstrate that temperature significantly influences the viscoelastic behavior of asphalt mixtures, and optimal material selection effectively enhances long-term pavement performance. This research provides practical guidance for pavement structural design and material optimization.
