  • Abstract:
    A falling weight deflectometer (FWD) is a device designed to simulate deflection of a pavement surface caused by a fast-moving truck. The FWD generates a load pulse by dropping a weight onto the pavement surface. This load pulse is transmitted to the pavement through a 300 (mm) 11.8 inch diameter circular load plate. The load pulse generated by the FWD momentarily deforms the pavement under the load plate into a dish or bowl shape. Envisioned from a side view, the shape of the deformed pavement surface is a deflection basin.
