Maintenance budget planning: A case study for rigid pavement maintenance system in Thailand

The expansion of rigid pavement network under the responsibility of the Department of Rural Roads (DORR) has driven DORR to initiate the development of Rigid Pavement Maintenance System (RPMS). The developed system is aimed to analyze concrete or rigid pavement conditions, select the most appropriate treatment technique, and prioritize importance of the maintenance to be performed on different road sections in order to optimize the DORR's limited maintenance budgets. The system consists of two modules: Pavement Condition Index (PCI) Module and Optimization Module. Deterioration data, obtained from the visual roads survey of pavement conditions, are collected and analyzed using the PCI Module. The Optimization Module allows the DORR to effectively arrange the maintenance for all concrete pavement sections. In addition, the rigid pavement performance criteria and the maintenance budget planning are discussed in this paper.
