There were interaction and coupling effects between the sensing element and the stress state of asphalt pavement matrix materials during pavement monitoring, and the pavement materials′ damage also affected the test results. In order to achieve the purposes of long life and high performance of recycled asphalt pavement, the ABAQUS software platform was used to establish a finite element model of structural rut plate embedded in tensile and compressed optical fiber Bragg and grating sensors. The influence of the sensor on the mechanical parameters of the specimen and the influence of the combination of the sensor′s module and the matrix materials′ modulus on the stress field and strain field of the specimen were obtained based on the study. The results show that the sensor has a certain impact on the local stress, strain and long-term creep behavior of asphalt mixture around the sensor, which is related to the modulus of the embedded sensor and the distance between the Matrix Materials and the sensor.
