Bridges reflect people’s longing for a better life. They facilitate daily travel as road throat, and connect different regional economies as economic bond. In addition to crossing gorges and chasms to aid rural reconstruction, they are also urban landscapes beautifying people’s lives. China, home to a total of over 1.2 million bridges, ranks first in the world as a veritable bridge country. This application project breaks the technology monopoly, filling the domestic gap of patented technology, and inventing ultra-high performance concrete (UHPC for short) necessary for achieving the new system. Deep application of maximum density theory, crack resistance and toughening theory, nano modification theory has increased the compressive strength by 4 times and the flexural strength by 10 times.
