Pavement layer structure and layer material property data play a key role in the development of pavement performance models, pavement design and analysis procedures, diagnostic evaluation of premature pavement deterioration, and selection of cost-effective maintenance/rehabilitation alternatives. This paper describes system design considerations for the end user interface and analysis requirements related to pavement material property database management. Case studies of material database development and implementation include the long-term pavement performance (LTPP) studies of the Strategic Highway Research Program, network-level pavement management applications on the state level, and a recent United Nations highway maintenance management project. Reference is made to the steps taken to ensure quality assurance, database integrity, and database security. Relational data-base tools provide an excellent facility for system development that should consider a number of key identifiers. The most important property data are the historical material data of all layers at the time of construction. For pavement management applications, the scope and data categories are limited and dictated by the end users and economic considerations.
