沥青稳定碎石柔性基层路面是目前国际沥青路面界的研究热点。柔性基层厚度和模量是沥青路面结构设计中的重要参数。沥青路面的基层材料种类繁多,基层各设计参数变化范围很大,而其设计参数对路面结构力学有重要的影响。文章选取典型的大粒径沥青稳定碎石柔性基层沥青路面结构,选用标准荷载,建立三维有限元路面结构模型,分析基层设计参数变化时的力学响应。分析结果为设计柔性基层沥青路面提供了力学理论基础。
Asphalt stabilized gravel flexible base pavement is the hotspot in the field of international asphalt pavement. The thickness and modulus of flexible basement are important parameters in the design of asphalt pavement structure. Asphalt pavement a wide range of grass-roots materials, grass-roots design parameters vary widely, and its design parameters of pavement structure mechanics have an important impact. In this paper, the typical asphalt pavement structure of large-diameter asphalt stabilized gravel flexible base is selected. The standard load is used to establish the three-dimensional finite element pavement structure model, and the mechanical response of the base design parameters is analyzed. The results provide a theoretical basis for the design of flexible asphalt pavement.
