An efficient database structure is the key to the success of a pavement management system.  A well-organized database can provide valuable and adequate information for pavement network management purposes with convenience and efficiency.  Thus, the main objective of this study was to develop a prototype database structure for “network level” pavement management using the concepts of “uniform section” and “dynamic segmentation.”   Relational database structure of a commercial software package was adopted in this study for the ease of recording and updating.  A systematic approach using various sorting and matching techniques was developed to overcome the current deficiencies of such relational databases based on the principle of “dynamic segmentation” to automatically generate summarized uniform section databases.  In addition, the applicability of various commercial Geographic Information System (GIS) software packages for pavement network management was investigated.  Furthermore, this study strives to integrate and enhance the prototype TKUNET program for the optimization of pavement network rehabilitation alternatives and budget allocations of Taiwan’s highways.  Thus, this study includes the following major tasks: (1) Investigation of new technologies in pavement management system; (2) Development of prototype network pavement dynamic segmentation  2databases; (3) Application of Geographic Information System (GIS) to pavement management; and (4) Integration and optimization of pavement rehabilitation alternatives.  The proposed approach has been implemented in a Windows-based program with many user-friendly interfaces for recording, updating, summarizing, query and reporting of the pavement databases as well as assisting high-level pavement management officials in conducting alternative rehabilitation strategies selection.  Finally, a practical case study was conducted to validate the results and applicability of this prototype program.  The completion of this study will, hopefully, provide a sound basis for future development and integration of our domestic network pavement databases and network optimization analysis to assure the best use of our limited resources.
