RISModeling of the FWD Deflection Basin to Evaluate Airport Pavements
Publisher: American Society of Civil Engineers
Abstract: The falling weight deflectometer (FWD) testing develops a deflection basin on the pavement surface. Depths of this deflection basin from the center of the falling weight are measured at different radial offsets. These ...
Neural Network–Based Thickness Determination Model to Improve Backcalculation of Layer Moduli without Coring
Publisher: American Society of Civil Engineers
Abstract: Traditionally, deflection data from a falling weight deflectometer (FWD) test and thickness data from pavement coring are used to backcalculate layer moduli. In this study, instead of coring, a neural network (NN) model ...
