Double-Deck Delight: Paving the Runyang Bridges

China will celebrate the completion of the latest of its many world class bridge projects with the opening of the Runyang bridges in July 2005. The 758 m long cable stayed bridge and the 1490 m main span suspension bridge, which together with the 1512 m long connecting viaduct form an impressive engineering achievement, were the subject of the largest ever orthotropic bridge deck paving project High summer temperatures and low winter temperatures have been responsible for numerous durability problems with pavements on orthotropic steel decks in China. The Runyang Bridge Construction Command conducted a thorough investigation of available materials, and chose Chemco Systems' epoxy asphalt based on problem free experience as the pavement. Fatigue tests demonstrated the ability of the epoxy asphalt pavement to resist fatigue cracking over the longitudinal stiffeners in the orthotropic steel deck. Epoxy asphalt is a thermoset polymer that does not soften as much as bituminous pavements at high temperatures and has shown no signs of rutting an shoving at very high deck temperatures
