摘　　要：本文对《公路沥青路面设计规范》(JTG D50-2006)中沥青路面结构验算方法使用的背景和实际工作中存在的问题进行了分析,结合17版新规范中取消弯沉值作为设计指标,采用基于多指标体系的设计方法进行沥青路面结构验算的设计方法,对沥青路面结构进行深入研究,以建立更加科学的公路路面结构层设计和检验方法,并为解决目前公路沥青路面结构验算中使用弯沉值作为设计指标与实际工程工作脱节的问题提供技术手段。Based on the analysis of the background and problems in the practical work of the checking calculation method of asphalt pavement structure in 2006 edition of the Code for the Design of Highway Asphalt Pavement,this paper uses the design method of checking calculation of asphalt pavement structure based on the design method of multi index system and cancels the deflection value as the design index in the 17 edition of the new code in order to establish a more scientific design and inspection method of highway pavement structure layer and provide a technical means to solve the problem that the deflection value is used as the design index in the calculation of highway asphalt pavement structure,which is disconnected with the actual engineering work.

关 键 词：路面结构 验算设计 弯沉值 多指标体系
