| Abstract | The Bridge Management System is designed to maximize use of available data and determine the optimal strategy to perform necessary improvements to bridges in the most cost-effective manner. This study intends to develop the bridge deterioration prediction models to forecast the conditions of concrete highway bridges at any time of remaining service life. A systematic approach of bridge condition ratings and inspection methods is developed. It proposes a rating system to assess separately the physical condition of individual bridge elements known as the segmental assessments. The method is suited to use in practical operations for inspecting and rating the existing conditions of concrete highway bridge under the responsibility of Thailand DOH. Comprehensive analysis by this method will reveal all element distresses with descriptions of damage types, severity and extent levels in any bridge component. To determine a Bridge Condition Score (BCS), the hierarchy of assessment is divided into 4 levels: member, element, component, and structure levels. The existing condition of inspected bridge elements integrated with descriptions of aggressive environments encountered and bridge inventory information in the database can be applied to generate deterioration models for bridges in the network. Various potential environmental factors affect the deterioration behaviours of each bridge elements are classified and analyzed. Deterioration patterns represent predicted conditions in future time of each bridge elements under different factors are determined by applying the Regression Method. Strategic maintenance plans in timing and execution will be properly determined by considering the proposed deterioration prediction models. Recommendations from bridge experts reveal that the proposed rating system is robust, possible in actual practice, and suitable for efficient application in evaluating the nation’s concrete highway bridges. Although the bridge condition rating was developed in response to the specific characteristics of Thailand’s bridges, the proposed methodology can easily be extended to other bridge agencies. |
