| 摘 要： | 未处治粒料具有显著的非线性特点．因此设计模量取值时需考虑路面结构参数的影响．采用正交方法对影响沥青路面粒料基层应力状态的路面结构参数进行了分析，认为上覆层厚度和土基模量是影响粒料基层弹性模量的关键因素．并给出了粒料基层弹性模量取值方法，较目前的经验取值方法更为合理．

| Abstract: | Resilient modulus of unbound granular materials is influenced strongly by stress level. So pavement structure parameters must be taken into account in modulus determination. The module of subgrade, the thickness of granular base and the module and thickness of cover layers,which influence the stress level and modulus of granular base, are analyzed with orthogonal method. The results show that the module of subgrade and the thickness of cover layers have great influences on modulus of granular base. Moreover, a modulus determination nomogram of granular base is developed, which is more rational than experiential method. |
