Heavy duty pavements are pavements subjected to the extremely heavy wheel loads associated with freight handling vehicles in industrial facilities, such as container terminals and warehouses. Heavy duty pavement need to handle many types of freight handling vehicles, such as forklifts, straddle carriers, gantry cranes and side loaders. The purpose of pavement design is to determine the number, material composition and thickness of different layers within a pavement structure required to accommodate a given loading condition.
