State Departments of Transportation, including the Texas Department of Transportation (TxDOT), have long been moving towards the development and implementation of pavement management systems that would enable monitoring of the performance of their roadways, as well as assist transportation officials with maintenance budget allocation and planning decisions. This report presents a new approach to the development of such a decision-support system with its focus on maintenance management for TxDOT. The new system is web-based and provides functional capabilities that allow transportation officials and engineers to make informed decisions regarding their budget planning and budget allocation for pavement maintenance management, fully utilizing available historical data. The developed system has successfully supported some of the TxDOT Districts in the development of their 4-year pavement management plans. In addition, pavement conditions in Texas were analyzed in terms of the effectiveness of the 4-year pavement management plans.
