摘要: 本文在充分考虑碎石基层非线性特性的基础上，采用弹性多层体系迭代方法全面分析了具有碎石上基层的半刚性沥青路面路表弯沉、面层底面及半刚性基层底面弯拉应力，建立了路面结构层厚度与路面抗疲劳寿命的关系，并在此基础上提出了适应于重交通道路的碎石基层半刚性沥青路面合理结构。

Abstract: In the paper, based on the nonlinear property of granular base, the superposition method of multilayer elastic system analysis is employed to analyse surface deflection, flexural tensile stress at the bottom of asphalt surface layer and semi rigid base course. Simultaneously, the relationship between thickness and fatigue life of pavement is established. Eventually, the thickness of semi rigid pavement with granular base, which is suitable for heavy traffic and shows excellent performance of resistance to fatigue, is proposed.
