The management of the asset components of the transportation system infrastructure is crucial to ensure active operation, suitable level of safety and security within budgetary constraints. For this purpose, the full knowledge of the characteristics of road network elements is required, including its history, both current and predicted future conditions through deterioration models – the fundamental module of infrastructure management systems. This article describes the main prediction practices of management of the Brazilian road bridges and evaluates the effectiveness of the existing inspection methodologies to forecast bridge deterioration rates using Markov chain method. Deterioration rates were estimated by using the available data collected in bridges inspections carried out in São Paulo State’s roads, based on the most common practices. The presented results required improvements in bridge inspection methods in order to enable improvements to advanced management approaches and increase the quality of the Brazilian entire road network.Downloads
