deck bridge
6.To improve the binding strength between the deck slabs and deck surfacing layer of Badong Changjiang River Highway Bridge and to provide the surfacing layer with anti-cracking ductility, a series of technical measures has been taken in the construction of the deck surfacing of the Bridge, including those of embedding binding reinforcement in the deck slabs, spraying inorganic binding agent between the slabs and layer, replacing part of the cement with micro expansion agent and adding appropriate amount of polypropylene fibers to the concrete.
7.In order to find the most unfavourable working position of steel deck pavement, the strain distribution test on site was carried out on all critical working place of steel deck of Jueshi Large Bridge in Shantou before and after the steel deck being paved, and has been compared with the results of the finite clement analysis.
