【摘要】 采用分形理论、层间接触理论,建立了沥青路面(面层/基层)层间接触模型,从微观上对沥青路面层间接触状态进行了分析.根据级配计算了沥青路面层间接触面积临界值的大小,提出了依级配定量计算沥青路面层间接触面积的方法,并分析了沥青路面微观结构与宏观路用性能之间的关系.更多还原

【Abstract】 In order to simulate the contact state of actual pavement structure layer more accurately,fractal characteristic theory and interlayer contact theory are used in combination to establish the interlayer contact model,and the microcosmic structure state of asphalt pavement of flexible base is analyzed.Meanwhile,according to grading,interlayer contact area critical value between surface layer and base layer is calculated,and a quantitative method based on grading is also put forward to calculate the contact area of pavement structure.Thus the relationship between pavement microstructure and pavement performance may be analyzed clearly through this method.更多还原
