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 摘要巴东长江公路大桥桥面铺装,通过采取预埋桥面粘接钢筋、喷涂无机界面粘结剂、用微膨胀剂替代部分水泥、在混凝土中掺入适量的聚丙烯纤维等措施来提高桥面板与铺装层间的界面粘结强度和给桥面抗裂增韧。
