Dr. Wang’s research interests focus on automated technologies for pavement survey and pavement data systems for design and management. In particular, automated cracking survey has been a main thrust of his research in the past 15 years, including developing 3D laser based imaging sensors, algorithms and computer implementations of database management and imaging processing of transportation assets, hardware integration and geographical positioning of data. His early work includes optimization and Markovian process for pavement management. In the recent years, a primary work conducted by Dr. Wang’s team includes database support for the MEPDG and DARWin-ME pavement design systems that will become the next-generation of pavement design procedure. Dr. Wang recently started working on developing technologies to establish geographically true 3D virtual pavement surface at 1mm resolution that can be used for variety of analysis on pavements, including distress and profiling surveys and surface characteristics for safety.
