Abstract

Technology on pavement monitoring has been paid more and more attention by government, engineers and scholars. Conventional methods, such as artificial inspection and core sampling, have defect in low efficiency and limited coverage, and modern technologies, such as spectrum analysis and integral imaging, have poor resistance to external interference and high cost, which reveals that common approaches have fallen behind the development of road engineering. Therefore, a novel raw material-encapsulated FBG strain sensor is put forward, thinking over outstanding advantages of fiber Bragg grating and perfect incorporation between coating layers and host layers. Numerical analysis and experiments have been done to inspect behavior of the sensing system. Results indicate that it can well detect the actual performance of pavements, and the sensor presents a high-precision, real-time and long-term monitoring, owning function of road disaster warming, which promise it an extensive future in pavement monitoring.
