Airfield pavement deterioration assessment using stress-dependent neural network models [PDF]
, 2009 In this study, an artificial neural network (ANN)-based approach was employed to backcalculate the asphalt concrete and non-linear stress-dependent subgrade moduli from non-destructive test (NDT) data acquired at the Federal Aviation Administration\u27s ...
