The Analysis of the Thickness of the Layers Influence on Graded Broken Stone Stress State

Abstract:

Graded broken stone has good road performance and it gradually began to adopt in strengthening the domestic old road or the new road design, because it is the repose of aggregate materials ,can effectively prevent the occurrence of reflection cracking and has good bearing capacity. Graded broken stone material has obvious stress dependent characteristics and the stress strain curve is nonlinear variation. Stress state and its place in the structure of pavement layer, layer thickness and modulus of the structure are directly related. Therefore, the paper has analyzed the thickness of each layer in the design of reinforcement structure impacting on the grading macadam stress state.
