FWD-falling weight deflectometer highway testing equipment KUAB

FWD test is carried out in order to find out the structural capacity of the road pavement. The Road Development Authority conducted the experiment.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.
This load pulse is transmitted to the pavement through a 300-millimeter (mm) 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.
Based on the force imparted to the pavement and the shape of the deflection basin, it is possible to estimate the stiffness of the pavement by using various computational methods. If the
thickness of the individual layers is also known, the stiffness of those layers can also be calculated.
