Research Progress on Fiber Bragg Grating Sensors in Road Testing and Engineering

To test pavement internal temperature, humidity, stress, strain and other parameters has been the focus and difficulty problem in the field of road tests.With the development of fiber optic sensing technology, it provided a new method for the road testing field.To demonstrate the feasibility that FBG sensing technology applied in the field of road tests, introduced the basic structure of the FBG sensing system, and started at temperature and strain sensor basic principle to summary the outcomes of actual temperature and strain tests that applied FBG sensors.Finally, the application of FBG sensors in other projects, including bridges, tunnels and airport runways is introduced.What'more, analyzed the difficulties and direction of promoting the use of FBG in the road testing projects.
