Simplified Approach for Structural Evaluation of Flexible Pavements at the Network Level

Corresponding data set for Tran-SET Project No. 17PUTA02. Abstract of the final report is stated below for reference: "Currently, there are few available simple procedures to identify structurally weak pavement sections utilizing Falling Weight Deflectometer (FWD) data at the network level (e.g., city, state or province). A simple method is required to determine the structural condition of pavement sections that can be directly implemented and automated in current pavement databases. The objective of this research study is to develop a simple analysis method to determine the structural condition of pavement sections utilizing the currently available non-destructive testing (NDT) deflection measurement devices at the network level that can be directly implemented and automated in the database of a typical transportation agency. In addition, the study had conducted an advanced mechanistic analysis to mimic the FWD deflection bowl obtained from the field. The developed structural condition parameters can be easily implemented in pavement management systems (PMS). This will aid Departments of Transportation (DOTs) and local highway agencies to make more informed decisions about the most suitable maintenance and rehabilitation strategies. Those parameters were also utilized to predict the remaining fatigue lives of the studied pavement sections."Tran-SET项目第17PUTA02号对应数据集。以下为最终报告摘要供参考：“目前，在路网层级（如城市、州或省份级别）下，可利用落锤式弯沉仪（Falling Weight Deflectometer, FWD）数据识别结构薄弱路面区段的简易可用流程仍较为稀缺。亟需开发一种简易方法，用于评定路面区段的结构状况，且该方法可直接应用于现有路面数据库并实现自动化。本研究的目标为开发一种简易分析方法，可借助现有非破坏性测试（Non-destructive Testing, NDT）弯沉测量设备，在路网层级下评定路面区段的结构状况，且该方法可直接在典型交通管理机构的数据库中完成部署与自动化运行。此外，本研究还开展了高级机理分析，以模拟现场实测得到的FWD弯沉盆。所开发的结构状况参数可便捷地集成至路面管理系统（Pavement Management Systems, PMS）中，这将助力交通运输部门（Departments of Transportation, DOTs）及地方公路机构更科学地制定适配的养护与修复策略。上述参数还可用于预测所研究路面区段的剩余疲劳寿命。”
