A systematic review of steel bridge deck pavement in China

As an important part of steel bridge deck, the engineering quality and service condition of steel bridge deck pavement (SBDP) directly affects the capacity and operational efficiency of the bridge. This paper reviews the history of the development of SBDP in China over the past 20 years from the exploration stage, rapid development stage and prosperity stage. The development and application of SBDP at different stages are discussed in terms of materials, structure, design, performance evaluation, maintenance and rehabilitation, respectively. The advantages and disadvantages of different pavement materials and structures, and the application of different research methods are summarized. The review shows that the improvement of pavement materials and structures and the development of new materials should be further studied on the multi-scale to enhance the durability of pavement materials, so as to extend the service life of pavements. The design method of SBDP related to the synergistic effect of vehicle, pavement and bridge should be established, and the design concept and method standard of rigid base pavement structure should be improved and formulate a complete design standard. In addition, multi-disease intelligent identification system and equipment should be studied to track the entire course of disease development in real time. And it is necessary to develop appropriate algorithms to select and classify the complex data of disease and maintenance history.
