| 中文摘要 | 根据非洲刚果(布)国家一号公路实地实验数据,采用MEPDG软件进行建模,在实际荷载水平及路面材料性质下,分析超薄沥青路面早期病害的原因,变化各层材料弹性模量和厚度,对车辙深度和疲劳裂缝等指标对结构强度和早期损害的影响,取95%保证率下符合可靠性要求的结果.进一步分析路面结构对高交通增长率的抵抗能力强弱,提出针对降低超薄沥青路面早期损害的措施.; The ultra-thin asphalt pavement owns distinctive early stage disease such as early significant cracks and rutting since it has a thin surface layer compared to traditional pavement structure.The research establishes models to simulate National Highway 1in Congo(Brazzaville)by MEPDG software.Considering load level and pavement material properties,the research analyzes the reason of early disease in ultra-thin asphalt pavement.By adjusting the key factors of modulus and thickness of each layer,the simulation arrives at the 95%reliability requirements of pavement structural strength such as top-down cracks and down-top cracks and rutting.The research also proves the performance of various pavement structure to resist high traffic growth rate,and draws conclusions about reasonable indicator trends of ultra-thin asphalt pavement. |
