摘　　要：该文介绍了在编制中华人民共和国行业标准《城镇道路路面设计规范》(CJJ169-2012)过程中,借鉴国外与国内公路研究成果,并考虑城镇道路自身特点,完善沥青路面结构设计指标体系,首次引入了设计可靠度,形成了以路表弯沉值、柔性基层沥青层层底拉应变、半刚性材料基层层底拉应力和沥青层剪应力为设计指标的沥青路面结构设计方法,专门开发了城镇道路沥青路面结构设计计算系统(PDS-CJJ169)V1.0,申请了软件著作权(2012SR017789)。The article introduces the compiling process of the industry standard of the People's Republic of China-Town Road Pavement Design Criterion(CJJ 169-2012) by referring the studying result of highways at home and abroad,considers the own characteristics of town roads and perfects the asphalt pavement structural design index system.The design reliability is firstly introduced to form the asphalt pavement structural design method by taking the surface deflection value,flexible base asphalt layer bottom tensile strain,semi-rigid material base bottom tensile strain and asphalt layer shear stress as the design indexes.The town road asphalt pavement structural design calculation system(PDS-CJJ169) V1.0 is specially developed and the software copyright(2012SR017789) is applied.
