Jiangjundu Yellow River Bridge is a full-line control engineering of Shanxi-Henan-Shandong railway thoroughfare. Its construction progress and quality of bridge deck pavement of the steel truss is crucial to the scheduled opening and safe operation of the heavy haul railway,which is the first railway whose axle load reaches 30 t in China. Firstly,this paper provided a brief introduction to the optimal bridge deck pavement scheme of large span steel truss bridge. Next,a detailed description of the construction technology and control points was given,and the corresponding detection methods and treatment plan to the construction quality of critical control points were proposed. Finally,a comprehensive evaluation of the pavement performance proved this construction technology original and practical.
