Service Description: Falling Weight Deflectometer ( FWD ) is a device which drops specified load, controlled by the operator, onto a circular plate positioned on the pavement surface wheel path and measures the deflection of the pavement with seven sensors. These sensors are spaced at specified distance usually 30 cm apart in a series along the device with one sensor located directly over the point of loading. Deflection is measured in micro-meter. Based on the FWD deflection measurements, strength of pavement, elastic layer strength, finite element analysis, or other mathematical modeling techniques can be applied to estimate the resilient modulus, modulus of elasticity, remaining life of surface layer or other factors for the pavement, sub-base, and sub-grade layers. These values can be used to estimate the remaining structural capacity of the existing pavement and determine any additional requirement of structural overlay. Processed data from Ground Penetrating Radar (GPR) measurement. boundaries, material types and information about the accuracy of Layer the processing. Deflections from KUAB FWD measurement, raw data or normalized deflections. Other data from KUAB FWD measurement. Load, temperature, time and a few standardized parameters from visual inspection made during the FWD measurement. General numerical data. Any numerical data, for example friction, visual observations may separately be worked out from other program. All structural analysis from fwd deflection and other input from FWD is used for output from KUAB PVD FWD Analysis Programs. Analysis features.
