摘要 沥青路面向下扩展裂纹(Top-down Cracking,简称TDC)是导致沥青路面破坏的原因之一,也是目前道路工程领域研究的热点.为探讨TDC成因,建立了路面结构的三维有限元模型,并采用大型有限元软件进行计算.计算结果表明,在假定的车轮荷载作用下,路面结构最大剪应力发生在路面表层,位置在轮迹边缘,其大小接近或超过常温下沥青混合料的抗剪强度,是导致半刚性路面产生TDC的主要原因. Surface-initiated longitudinal cracking along wheel path(or Top-down Cracking) is not only one of the main damage types of heavy-duty asphalt pavement but also a fresh hotspot in the field of pavement damage focused.The authors developed a 3D finite element model to discuss the cause of TDC with large finite element software.The analysis shows that maximum shear stress which come into surface-initiated under wheel load is beyond shear strength of asphalt binder. So the authors consider the maximum shear str...
