SPR-4915: 3D GPR Applications for Network Level Testing

The main objective of this study is the integration of 3D GPR data with deflection data either from existing FWD or soon to be available traffic speed deflectometer (TSD). To relate deflection measurements to pavement health metrics such as the modulus of elasticity or the structural number, finite element analysis requires estimates of pavement layer thickness and pavement type information. This project will investigate the use of 3D GPR for layer thickness estimation and perform a sensitivity analysis to quantify the effect of errors in layer thickness estimates in structural number computation.
