The Model for Predicting the Remaining Service Life of Reinforced Concrete Bridges in-Service and Applicability

There is a strong need in maintenance and management of bridge that analyzes and predicts remaining service life (RSL) of reinforced concrete bridge. Since structural resistance of concrete bridge is generally suffered from environment, load and material etc. factors, which are intercoupled and time-varying. Hence researchers should consider the economic development of road traffic area, environment of operational bridge, variation of load, deterioration law of materials, and maintenance cost of LCC for predicting RSL of bridge. This paper reviews recent model of predicting the remaining service life (RSL) for concrete bridge and serviceability, analyzes model characteristic and defects, and looks forward to future research from the viewpoint of structure durability, reliability and life cycle cost, respectively.
