Research on the Application of Fiber Bragg Grating Sensor in Pavement Monitoring

Abstract:

Based on the fiber Bragg grating sensing principle, and according to the characteristics of asphalt pavements, two types of FBG sensors are designed. One type is rigid sensor packaged by steel casing which labeled as R-type, and the other one is flexible sensor packaged by rubber which labeled as F-type. Through the tests of sensing performance, high-temperature stability performance and low-temperature stability performance, a comprehensive analysis of the long-term service performance is obtained. Analysis show that both rigid and flexible packaing have sensitizing effect while flexible packaging is better. Both types of sensors have good high temperature stability and low temperature stability, while R-tpe is better than F-type.
