Evaluation of Seismic Pavement Analyzer for Pavement Condition Monitoring
Seismic Pavement Analyzer (SPA) is a device for nondestructive evaluation of pavements developed under the Strategic Highway Research Program (SHRP). One of the main objectives in the development of the SPA was to create a device that will allow measurement of onset of deterioration at early stages, and thus contribute to a more economic pavement management. Primary applications of the SPA include pavement profiling in terms of elastic moduli and layer thicknesses, detection of voids or loss of support under rigid pavements, delamination in rigid pavements and bridge decks, and subgrade evaluation. The SPA incorporates five seismic techniques for those purposes: Ultrasonic Body-Wave (UBW), Ultrasonic Surface-Wave (USW), Impact Echo (IE), Impulse Response (IR) and Spectral Analysis of Surface Waves (SASW). The SPA was evaluated for possible implementation in evaluation and condition monitoring of pavements in New Jersey. Specifically, the objectives of the study were to examine 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. To achieve the objectives of the study, a number of flexible and rigid pavements in New Jersey were tested. Specific attention was given to pavement profiling and detection of voids or loss of support under rigid pavements.
