Evaluating and Implementing Ground Penetrating Radar (GPR) for Continuous and Rapid Monitoring of Moisture Fluctuations in In-Service Roads

Summary:

Traditional methods for measuring pavement moisture, including in-place sensors and indirect assessments like FWD, can be costly, invasive, slow, offer limited spatial coverage, and disrupt traffic. In contrast, ground penetrating radar (GPR) offers a non-invasive, portable solution for swiftly evaluating extensive road segments, detecting subsurface moisture levels with reasonable cost, thereby supporting local road authorities in promptly assessing moisture conditions in critical pavement areas. The aim of this research study is to advance the validation and implementation of GPR-based pavement moisture assessments on actual low-volume roads.
