Investigator will thoroughly test and assess the Portable Seismic Property Analyzer (PSPA), a hand-held device that focuses on pavement layer properties. The device can be utilized on both rigid and flexible pavements. When used on rigid pavements, the PSPA can provide information with respect to the quality and thickness of concrete, the existence and/or the location of voids or delamination within concrete, and the existence of voids or the loss of support underneath the slab. For flexible pavements, the PSPA provides information about the quality of the asphaltic-concrete layer. |
