Analysis of pavement deflection sensitivity to variations in layer properties

Pavement surface deflections reflect the overall structural performance of the system. Deflection measurement data are often used in backcalculation procedures to estimate the properties of the layers, i.e., layer elastic moduli. In order to interpret the results of a backcalculation exercise properly, it is important to evaluate the sensitivity of the surface deflections to the property of each layer. The sensitivity of pavement surface …
