INVESTIGATION ON APPLICABILITY OF MOISTURE DETECTION TECHNOLOGY BETWEEN PAVEMENT LAYERS BY ELECTRICAL RESISTANCE

Rainwater and snowmelt water enter from cracks in the pavement and from the edges of pavement. These waters spread between the layers of pavement. And it causes delamination and potholes. Furthermore, the addition of freeze-thaw action to these accelerates pavement damage. Therefore, a technology that appropriately suppresses the ingress of water is required. The purpose of this research is to develop a technology to detect the moisture between layers of pavement. This technology is necessary to evaluate the performance of the technology that suppresses the ingress of water. In this study, the applicability of technology to detect moisture by measuring electrical resistance is discussed. Electrical resistance was measured using copper foil electrodes. Based on the various test results, it was found that the developed technology can be detected the moisture infiltrated between the layers of pavement.
