Embodiment
[0012] In this embodiment, the soil base, rigid or semi-rigid base, and bonded oil layer are the same as those of the prior art (omitted).
[0013] Calculated using the finite element method, the results show that the rutting depth of the asphalt pavement increases with the thickness of the asphalt pavement, as shown in Table 1:
