Pavement management is a process by which decision makers rationalize management decisions regarding a wide spectrum of activities: planning and programming of investments, design, construction, maintenance and rehabilitation, periodic evaluation of performance, and pavement research. In this context, management is defined as efficient coordination of the above activities in order to reach a systematic decision. The system reported herein is the result of the development and implementation of a third-generation pavement management system for the ohio department of transportation that has required slightly less than 4 years to complete. The pavement management system described is characterized as a network-level system that provides optimal actions for candidate pavements, long-range budget allocations, present assessment, and future forecasting of the network conditions and rehabilitation need. Various modules and submodules are manipulated to achieve optimal solutions over a 6-year planning period bymaximizing pavement performance for a given budget or by minimizingcost for a given network performance level.
