| 摘要： | Pavement ME Design (MEPDG/DARWin-ME) is a significant advancement in pavement design, but requires much more inputs from various sources. Through the transportation pooled fund study TPF- 5(242), a full-production software Prep-ME with comprehensive database features has been developed to assist state DOTs in data preparation and improve the management and workflow of Pavement ME Design input data. Prep-ME is capable of pre-processing, importing, checking the quality of raw Weigh-In-Motion (WIM) traffic data, and generating three levels of traffic data inputs with in-built clustering analysis methods for Pavement ME Design. A number of additional modules in Prep-ME may be useful to any highway agency, including those for climate, materials and FWD. The ultimate goal of Prep-ME is to be the companion tool that can seamlessly communicate with Pavement ME Design in a full production environment for the local calibration and implementation. This tool can be used by pavement design engineers to prepare input for Pavement ME Design, but also traffic engineers to collect better traffic data and manage those data for other applications. In addition, the 1- mm 3D laser imaging PaveVision3D Ultra technology developed by the research team has been demonstrated for the potential use of calibrating Pavement ME Design. |
