- Abstract:
-
In order to effectively suppress the interlayer failure of the old asphalt pavement plus pavement structure, a finite element model is established, and the influence law of the internal forces between the old asphalt pavement and the paving structure is determined by analyzing the horizontal load, the thickness and modulus of the additional layer, the equivalent rebound modulus of the old road, and the lateral cracking of the old road on the internal forces of the old asphalt pavement and the paving structure, and then determine the range of interlayer shear stress of the old asphalt pavement and the paving structure corresponding to different horizontal friction coefficients, and the interlayer compressive stress range of different pavement thicknesses. The research conclusion has reference value for the design of asphalt pavement plus paving structure and the technical index requirements of interlayer materials.
