| 摘 要： | 为分析当前高速公路严重车辙路段流动性车辙的影响因素,建立了沥青路面三维有限元模型.以沥青层的侧向(横向)位移为评价指标,分析了不同沥青层材料、不同沥青层结构组合及不同基层形式对流动性车辙产生的影响.给出了减少流动性车辙产生的对策;提出了沥青结构层协调组合设计的理念;指出了级配碎石联结层的使用不仅会减少高温下沥青上、中面层的侧向流动变形趋势,还会减小上、中面层的横向位移.

| 关 键 词： | 沥青路面 流动性车辙 侧向位移 泊松比 结构协调组合设计 |

| Abstract: | In order to study the reason of flow rutting of highway asphalt pavement with serious rutting, the three-dimensional FEM model was developed. Based on the evaluating indicator of lateral deformation, the influence of different asphalt layers materials, different structural combination of asphalt layers and different bases on flow rutting were analyzed. The countermeasure to lessen flow rutting is advanced and the design idea of coordinated combination design for asphalt layers is proposed. The use of binder course of graded broken stone not only decreases the trend of lateral flow deformation at high temperature but also reduces the lateral displacement of surface layer and middle layer. |

| Keywords: | asphalt pavement flow rutting lateral displacement Poisson's ratio coordinated combination design of structure |
