Research on ERS Steel Deck Pavement Techniques
Steel bridge deck pavement has been considered as a worldwide engineering problem, especially in China. During the past decade, many famous long-span steel bridges have been built in China, for example, Sutong Yangze River Bridge. However, some serious deterioration on the steel bride deck pavement happened when it was opened to traffic because of the heavy traffic and high temperatures. Based on the analysis on the construction problem of steel deck pavement and special traffic and environmental conditions in China, a new kind of steel deck pavement structure, called epoxy–resin–stone (ERS) steel deck pavement, is presented in this paper. It contains three main layers, i.e., epoxy bonding chips layer (EBCL), resin–asphalt mixture (RA05), and stone mastic asphalt (SMA). EBCL is introduced to act as a waterproof, bonding, and slipping proof layer; RA05 is used as an intermediate layer; and SMA is used as a surface functional layer. Test results and engineering practice show that ERS steel deck pavement has excellent performance and good workability. The technique has been applied in more than 10 steel bridges. It is helpful to solve the difficult steel deck pavement problem in China.
