- Abstract:
- Top-down cracking (TDC) is one of the causes of asphalt pavement failure, and it is also a hot spot in the field of road engineering. In order to explore the causes of TDC, a three-dimensional finite element model of pavement structure is established, and large-scale finite element software is used for calculation. The calculation results show that under the assumed wheel load, the maximum shear stress of the pavement structure occurs on the surface of the pavement, and the position is at the edge of the wheel track, and its size is close to or exceeds the shear strength of asphalt mixture at room temperature, which is the main reason for TDC in semi-rigid pavement.
