A highway network is valuable for the society it serves, and should be maintained so as to keep this value at an optimum level. This study was performed to contribute to the planning of highway pavement maintenance work, associated with the Pavement Management System application in Turkish State Highways. In this study, pavement performance was modeled, taking into consideration traffic loads, environmental conditions, and the longitudinal evenness value which is accepted as the pavement performance indicator by the General Directorate of Highways in Turkey. Then, using this model, it is planned to estimate the total maintenance costs (per lane-km) of Turkish State Highways according to maintenance year and type.
Key words: Pavement management, maintenance, modeling, state highways.
