A Sixteen-Year Review of Condition Survey and Analysis of Steel Deck Pavement on Jiangyin Yangtze River Bridge

Abstract

To obtain a complete picture of the steel deck pavement condition on Jiangyin Yangtze River Bridge, an on-site survey for different pavement structures was conducted to collect information regarding traffic volume and extents of pavement distresses, including gussaphalt pavement, gussasphalt lower plus epoxy asphalt above pavement and double-layer epoxy asphalt pavement. The pavement performance under the combination of heavy truck loading and extreme climate condition was discussed to summarize the technology requirements of orthotropic steel deck pavement. The research findings provide reference for orthotropic steel deck paving worldwide.
