Data for: Pavement Design for Local Roads and Streets

Low-volume roads (LVRs) make up more than half the centerline mileage in the United States, most of which are not designed. The Cornell University Local Roads Program worked with local highway agencies New York State to develop a mechanistic-empirical pavement design tool that overcomes the limitations of expertise and time of most LVR highway officials but takes advantage of the knowledge of their own LVRs. The tool developed, RoadPE: LHI, uses two common pavement fatigue criteria, surface tensile strain and subgrade vertical strain, with simplified inputs, and built-in trend analysis to determine the thickness of the asphalt layers for overlaid, mill and filled, rehabilitated, and reconstructed LVRs.

低交通量道路（Low-volume Roads, LVRs）占美国道路中心线总里程的半数以上，其中绝大多数未经过专门设计。康奈尔大学地方道路项目组与纽约州地方公路管理机构合作，开发了一套力学-经验法路面设计工具。该工具可克服多数低交通量道路管理人员在专业知识与时间投入上的局限，同时充分利用他们对自身管辖范围内低交通量道路的实际认知。所开发的这款名为RoadPE: LHI的工具，采用两种通用路面疲劳判定准则：表面拉应变与路基竖向应变，搭配简化输入参数与内置趋势分析模块，可为加铺、铣刨重铺、路面修复及道路重建的低交通量道路确定沥青层厚度。
