Evaluation of Seismic Pavement Analyzer for Pavement Condition Monitoring

Résumé du livre

The Seismic Pavement Analyzer (SPA) is a device for nondestructive evaluation of pavements. This study examines the applicability of the SPA in pavement structural evaluation, detection of defects and distresses, and other uses relevant for pavement evaluation and condition monitoring. With respect to the equipment itself, the objectives were to examine the robustness and consistency of the SPA hardware and software, and the soundness of the seismic methods implemented in the device. A number of flexible and rigid pavements in New Jersey were tested, with specific attention given to pavement profiling and detection of voids or loss of support under rigid pavements.
