However, within the range of 0–0.9 m, the mean deflection values of the sensor-equipped geogrid-reinforced section were 23.1–59.7% lower than those of the conventional section, and all differences were highly significant ( p < 0.001).
During the paving process of the asphalt pavement structure, the sensing geogrid strain and the corresponding optical fiber wavelength shift induced by a single rolling pass of the roller exhibit a decreasing trend with the increase in asphalt coverage thickness, and significant differences exist in the influence of different compaction equipment.
