Abstract: This study establishes a mechanical calculation model based on the structure of cement concrete pavement, and calculates and analyzes the mechanical response of the cement concrete pavement in the use stage and the early shrinkage deformation stage. The results show that the interlayer interaction has little influence to the concrete pavement in the use stage. The limitation of the interlayer interaction on the early shrinkage deformation of the surface layer is the main reason for the crack at the bottom of the surface layer. Smooth interlayer contact should be ensured in the design of cement concrete pavement.
