摘要
目前,半刚性基层沥青路面频繁出现的早期破坏现象使半刚性基层在我国的适应性受到普遍关注。如何针对半刚性基层的不适应性对路面结构的影响,综合考虑荷载、车速、环境和路面结构等因素,深入分析半刚性基层在不同情况下的损坏机理,重点从结构方面增强半刚性基层的适用性,进而提高半刚性基层的结构疲劳寿命,并在此基础上对路面结构设计指标和参数做出优化,是现阶段亟需解决的问题。
     通过对不同地区半刚性基层沥青路面损坏情况的调查,结合已有文献和现场调查,分析半刚性基层的典型损坏模式和破坏过程,在此基础上对半刚性基层的适应性进行分析,并提出沥青路面半刚性基层的控制破坏模式。在对影响裂缝产生的因素进行分析的基础上,运用有限元软件对路面结构进行数值模拟,分别对荷载、温度、耦合作用及车速作用下的层底应力进行分析,然后分别对路面结构在不同接触状态和基层不同层位时的层底应力进行对比研究,结合半刚性基层不同结构类型和施工工艺对基层的影响,从如何减少路面裂缝的角度提出了半刚性基层在路面结构中的合理应用方式。根据对影响车辙因素的分析,运用有限元软件对路面结构进行数值模拟,分别对荷载、温度、耦合作用及车速作用下的剪应力进行分析,然后分别对路面结构在不同接触状态和基层不同层位时的剪应力进行对比研究,从如何减少路面车辙的角度提出了半刚性基层在路面结构中的合理应用方式。然后通过有限元软件建模对荷载单独作用和耦合作用下带裂缝的路面结构层进行应力强度因子计算,并拟合半刚性基层的结构疲劳寿命,结合不同温度和基层模量及裂缝长度下的基层寿命变化,得出了裂缝扩展规律,提出了能够延长半刚性基层结构疲劳寿命的基层模量范围和沥青面层厚度范围。
     论文最后对目前我国沥青路面设计方法进行总结,并分析设计方法中存在的不足。在针对半刚性基层适应性的基础上,综合考虑荷载、温度、车速及接触状态等因素对路面结构受力的影响,提出了半刚性基层的合理使用方式,并提出了半刚性基层沥青路面的设计控制模式和设计及验证指标,在此基础上推荐了基于半刚性基层适应性的沥青路面结构组合设置。
At present the early damages in semi-rigid asphalt pavement make it a concerned problem that if semi-rigid base can continue to be used in China. It is a pressing problem how to enhance the adaptability of semi-rigid base from the aspect of pavement structure and improve its structural fatigue life, and then on base of them the design index and parameter are optimized. In order to research the target, the load, vehicle speed, environment and pavement structure should be comprehensively considered, and damage mechanism of semi-rigid base in different conditions should also be deeply analysed, which are both according to inadaptability of semi-rigid base and service life of asphalt pavement.
     Based on the spot investigation of semi-rigid asphalt pavement and existing documents, the main damage mode of pavement is analysed and then damage mode needed to be controlled is proposed which is on the basic of adaptability analysis of semi-rigid base. On the base of factors analysis effecting on cracking, the forces of pavement structure are analysed through numerical simulation in different load, temperature, coupling effect and vehicle speed with finite element software, which is also analysed in different contact states and base positions. Combined with different base structure and construction technology of semi-rigid base, reasonable using mode of semi-rigid base in pavement structure are advanced from the view of cracksing resistance. On the base of factors analysis effecting on cracking, the shear stress is analysed through numerical simulation in different load, temperature, coupling effect and vehicle speed with finite element software, which is also analysed in different contact states and base positions. Then the reasonable using mode of semi-rigid base in pavement structure is advanced from the view of rutting resistance. Using the model in finite element software, the crack tip stress intensity factor is calculated under independent load action and coupling effect, and then the structural fatigue life of semi-rigid base is fitted using formula of Paris. Combined with the change of structural fatigue life under different temperature and base module, the crack propagation law is proposed and the base module area and surface thickness are advanced which can extend the base fatigue life.
     Then the design methods of foreign and domestic is summarized and contrasted and deficiency in the design method is pointed out. The reasonable using system and design index and control model are proposed which is on base of semi-rigid base adaptability and stressing influence is comprehensively considered under different load, temperature and speed and contact state. Then on this basis the structure establishment of pavement structure is proposed which is based on the adaptability of semi-rigid base.
