Early damage to the deck pavement has become a major disease that affects the function of the expressway to exert and induce traffic accidents. The paper analyzes the possible situations that may occur in the construction of bridge deck pavement in Zhengzhou Huanghe Second Bridge and analyzes the pertinent measures which need to be timely taken. The preparation of waterproof adhesive layer and asphalt concrete pavement, the control points of construction process and the basis and standards of quality inspection were systematically introduced. The paving and rolling processes of asphalt were also studied in depth.
