| Abstract | In a good pavement management system, it is essential to identify and to predict the pavement transition characteristics and it requires an approach which incorporates pavement pe1formance and effect of maintenance actions. Such a system should have a maintenance action selection technique or method, where selection is done based on the minimization of total cost or maximization of total benefit. The main objective of this research was to develop such a management system that prepares optimized pavement maintenance schedule for the road networks under the Department of Highways (DOH), Thailand. As a result, data and information used in this research were acquired from DOH. Total roads were grouped into eight groups according to the traffic volume and pavement surface conditions were classified into five states according to the roughness conditions. An optimized pavement maintenance schedule for the flexible road pavements of DOH road network was prepared. This schedule was developed by using stochastic nature of pavement behavior. As a stochastic process, Markov chain model was developed to identify and to predict pavement deterioration characteristics. Because of inadequacy of relevant data, transition probabilities were identified by some reverse techniques. These probabilities represent the deterioration behavior of those pavements. A Dynamic Programming (DP) model was developed to minimize total costs as an optimization model. Total cost includes cost of various maintenance actions and vehicle operating cost associated with the pavements. Optimized maintenance schedule prepared by DP model was almost similar to that of prepared by Highway Design and Maintenance Standards Model (HOM-Ill). It was identified that DP model has some merits and hence it was recommended that DOH can practice this approach with sufficient pertinent data. |
