Abstract
The Hangzhou Bay Bridge is located at the typical marine corrosion environment. Research on the durability of reinforced concrete acts as an important role to evaluate the service life of the bridge. In order to evaluate the durability of Hangzhou Bay Bridge, the field exposure station of Hangzhou Bay Bridge was built during the construction of Hangzhou Bay Bridge in 2005. Hundreds of concrete specimens were placed at the station for at least 10 years, the chloride ions inside the concrete were tested twice per year. This paper summarized the experience of constructing and maintaining for the field exposure station. Meanwhile, the application of information construction and management of the exposure test station to evaluate the durability of the bridge is introduced.
