- *Abstract
-
Currently, many nondestructive mechanisms such as SASW (spectral analysis of surface wave) and MASW (multichannel analysis of surface wave) for detection of subsurface pavement profiles have been used. However, these approaches are associated with possible limitations such as detection limited only to point tests (moving test not feasible), slow assessment and analysis, and absence of real-time profile generation. This novel sensing system enables generation of payment profile on real-time basis using air coupled surface waves.
