- Abstract
The study on the coordination deformation between asphalt mixture and Fiber Bragg Grating strain sensor (FBG) is the precondition and foundation to solve the problem of FBG application in pavement. According to the two kinds of FBG developed recently (they were classified into three categories based on the application features), we designed an accuracy evaluation testing method for FBG and asphalt mixture coordination deformation, and conducted the strain test of asphalt mixture by static loading and dynamic loading. The result indicates that using FBG after strain modification to measure the internal stain of the pavement structure is feasible. Compared with other kinds of sensors, module matching FBG has a better test effect, and this kind of FBG is able to reflect the accumulative deformation of asphalt mixture to some extent.
