SUPPORT OF PAVEMENT MANAGEMENT SYSTEMS AT THE DELAWARE DEPARTMENT OF TRANSPORTATION

This report is presented in three parts. Part I provides a background on pavement management systems and includes highlights of the research and literature review component of this project. Part II discusses the foundations of pavement management systems in terms of the data collection, modeling, and optimization that are involved. Part III discusses the specific work and analysis performed for this project in addressing the following questions: What is the state of current pavement management systems at the Delaware Department of Transportation? How is the Overall Pavement Condition (OPC) index derived and will it support road surface performance modeling? What are the appropriate factors that should be considered for derivation of an OPC index and for performance modeling, and what is the current availability and accuracy of data for Delaware? What are appropriate performance models? How can pavement management systems be implemented?
