| Abstract: | Fiber Bragg grating(FBG)is packaged by a compound containing epoxy resin and toughening agent mixed in certainmass proportion.The packaged FBG performs a good lineariy,the correlation coefficient reaches 0.99.The strain and temperature sensitivity coefficients reach 1.8 pm/10-6 and 144.9 pm/℃,Compared with the naked FBG,the strain and temperature sensitivity coefficients are increased 1.64 and 14.3 times respectively,The compressive strength of the packaged FBG is 70 MPa.These performances will completely satisfy the requirement of monitoring asphalt concrete pavement. |
