Optimization Study on Paving Structure of Steel Bridge Deck Suitable for the Chinese 2th Climate Zone

Abstract:

The six types of bilayer paving structures were composed based on the characteristics of the three most common paving materials in the article. And tests of high-temperature stability and low-temperature fracture resistance were done according to the climate conditions of Tianjin City, thus providing technological references for choice of paving material of steel bridge deck in the Chinese 2th climate zone. The testing results show that: the paving structure of 2.5cm SMA above and 2.5cm epoxy asphalt mixture below is optimal in the comprehensive indexes of technology and economy, it's the suggested paving form of steel bridge deck suitable for the Chinese 2th climate zone.
