A Long Life Pavement for Orthotropic Bridge Decks in China

Pavements on orthotropic steel bridge decks in China have typically lasted three to seven years until the introduction of Epoxy Asphalt at the 2nd Yangtze River Bridge at Nanjing. The thermoset nature of Epoxy Asphalt compared to the thermoplastic bitumen paving materials previously used accounts for its ability to satisfy the requirements of skid resistance, a uniform riding surface and steel deck waterproofing for extended years even under severe ambient and load conditions. As of the end of 2008 over 500,000 square meters of Epoxy Asphalt have been installed on 20 orthotropic steel bridges in China. These installations are performing very well with few problems. Extensive laboratory test programs have been conducted to characterize the properties of this unique paving material. Although there are strict time and temperature constraints in the construction of Epoxy Asphalt pavements Chinese contractors have quickly learned how to install these pavements without significant problems.
