Abstract

Non-destructive prediction of pavement layer thickness and material properties is described in this paper. Three non-destructive evaluation (NDE) techniques are applied and evaluated through field tests carried out on various full-scale pavements. The pavement sections vary in material type, thickness, inter-layer bond condition and underlying base material type. The following NDE methods are considered: conventional and modified impact-echo, multi-channel analysis of surface waves (MASW), a hybrid seismic/guided wave method, and ground penetrating radar (GPR). The evaluation of MASW data is based on a Lamb wave approach in frequency domain utilizing both propagating and non-propagating waves. In the hybrid seismic/guided wave method the velocity of guided waves is evaluated in time-domain and the thickness is estimated from the combined measured velocity and resonant frequency of the Sl Lamb wave. The technical bases, equipment, data interpretation and field testing procedure are described for each method. The NDE results are presented and compared to ground-truth core samples. The performance and accuracy of the NDE methods are presented for each pavement type.
