摘要：	This report summarizes the requirements for development of a long-term pavement performance (LTPP) program for the state of Texas. This work is part of a project sponsored by the Texas Department of Transportation to develop distress prediction models for rigid pavements which are to be incorporated in the Texas pavement management information system (PMIS) currently under development. As in other pavement management systems, test sections are identified for which distress data can be collected to develop the required models. An experiment design which keeps in view the existing LTPP and Center for Transportation Research (CTR) experiment designs is described. The recommended experiment designs meet the current pavement design standards, latest research criteria, and climatic and geographic needs of Texas. The experiment design is followed by a discussion of the type of data which should be collected. The data items to be collected are divided into two categories: (1) inventory data items and (2) monitoring data items. Inventory data item sources are also identified. The human and financial resources required to establish the database and maintain and monitor it periodically are also evaluated.
