| 摘 要： | 层间结合状态是影响路面结构力学和使用性能的重要因素。鉴于当前我国沥青路面设计规范中路面层间的完全连续状态假定存在缺陷，采用Goodman模型对路面层间结合状态进行描述，通过BISAR3．0软件计算和对比了不同层间结合状态条件下的路面结构力学响应，并结合结构力学指标进行路面性能分析和寿命预估。结果表明：层间结合状态由连续变化为光滑过程中路面力学指标、使用寿命和服务水平将处于不利状态。

| Abstract: | Interface condition is one of the most important factors for structural response and performance of asphalt pavement.By considering the assumption of full-friction in the Chinese specification of asphalt pavement is an obviously drawback,in this paper different interface condition is formulated by the Goodman model and structural response of asphalt pavement is calculated.The results show that when the interface condition is transferred from full friction to complete slip leads to a rapid increase of struct... |
