The document outlines the development of a windows-based graphical user interface version of the 3D-Move software for pavement response analysis. Key features of the new software include the ability to model complex loading conditions from databases, generate asphalt mixture master curves from lab data, and output results in graphical and tabular formats. The new version aims to improve usability and running time compared to the original DOS-based version. Recommendations for future work include optimization of material models, inclusion of additional vehicle types, and modeling of pavement stresses under non-uniform loading conditions.
