Computed tomography (CT) scanning has attracted increasing attention as a non-destructive technique for evaluating the internal structure and performance of asphalt mixtures. Conventional performance evaluation methods generally rely on destructive mechanical testing and provide limited information about the internal characteristics of the material. In contrast, CT scanning enables high-resolution visualization and quantitative analysis of important structural features, including air-void connectivity, aggregate contact, and mastic coverage, which strongly influence the durability and mechanical performance of asphalt mixtures..
