The world has seen an explosive growth in renewable energy development activity in recent years, attributed to the significant technological advancements in green energy (e.g., wind and solar energy), alongside other emerging technologies. The development of wind farms requires movement of very heavy equipment and components on Farm-to-Market (FM) roads during installation and operation phases by Overweight/Oversize (OW/OS) hauling units. Such moves of OW/OS vehicles necessitate designing the FM pavements to have adequate structural capacity that can accommodate the heavy and slow-moving nature of hauling vehicle. The main objective of this study is the definition of a mechanistic-empirical methodology for the structural design of asphalt pavements in renewable energy plants.
