To improve the planning mechanisms of highway maintenance and rehabilitation, many agencies have resorted to pavement management systems built as simple optimization models. These models are generally inadequate because they are too inflexible. The core of the proposed system is a general Markov decision process structure in which administrative divisions of the highway network (regions, districts) are explicitly taken into account. This basic structure is stated in an equivalent linear programming format which then allows for the addition to the model of various linear constraints. The other fundamental element of the system is a formal descriptive framework which is made up of a network language and a scenario language. This paper describes both languages, the general Markov decision process structure, and the current computer implementation of the system. Planned future developments are also outlined.
