Description
Summary:With a population of roughly 6 million, Nanjing is one of the largest cities in China. Most of the city is on the southern side of the Yangtze River, but the northern side is developing rapidly. To alleviate the traffic congestion that has accompanied the city's growth, a new bridge, the Nanjing Second Yangtze River Bridge, has now been built to the 11 kilometers downstream. The $410 million bridge was designed by the Highway Planning and Design Institute -- a government agency based in Beijing. The girder for the cable-stayed segment of the bridge is a steel box with an orthotropic deck. Most of the girder was directed using the balanced-cantilever method. The work proceeded simultaneously in both directions from each of the 2 196 m tall diamond-shaped concrete towers. Meanwhile researchers conducted a comprehensive testing program to select the most suitable pavement system. In the end they chose epoxy asphalt pavement for its outstanding overall performance.
