The installation of waterproofing membranes on concrete bridge decks is a commonly used strategy to prevent water on the roadway surface from penetrating into the deck and to reduce the load and freeze–thaw related damage to the bridge deck. Typically, an asphalt layer is paved over the waterproofing membrane to prevent damage from heavy vehicles. The early failure of asphalt pavement overlays on concrete bridge decks with waterproofing membranes has been recognized as a significant issue by several transportation agencies. Potential reasons for the failure of the asphalt overlay were thought to be poor adhesion between the waterproofing membrane and the asphalt wearing course, and the material properties of the asphalt layer. By determining the most effective waterproofing methods and strategies, this research will serve to decrease repair and replacement costs, and increase the service life of asphalt overlays on concrete bridge decks. The main goals of this study are to provide the industry and transportation agencies with better insight into the failure mechanisms of asphalt overlays on concrete bridge decks and to establish field and laboratory experiments to evaluate the performance of these overlays. From the results of this study, a poured waterproofing membrane was recommended as an ideal membrane for use on concrete bridge decks because of its ease of installation, complete impermeability, and high bond strengths between the concrete deck, membrane layers, and asphalt overlay.

在混凝土桥面板上安装防水膜是一种常用的策略，可以防止路面上的水渗入桥面，并减少荷载和冻融对桥面板的损害。通常，将沥青层铺在防水膜上，以防止重型车辆损坏。几家运输机构已经认识到，带有防水膜的混凝土桥面板上的沥青路面覆盖层的早期破坏是一个重大问题。认为沥青覆盖层失效的潜在原因是防水膜和沥青磨损过程之间的粘附性差，以及沥青层的材料性能。通过确定最有效的防水方法和策略，这项研究将有助于减少维修和更换成本，并延长混凝土桥面板上沥青覆盖层的使用寿命。这项研究的主要目的是为工业和运输机构提供对混凝土桥面板上沥青覆盖层破坏机理的更深入了解，并建立现场和实验室实验以评估这些覆盖层的性能。从这项研究的结果来看，推荐浇筑防水膜作为混凝土桥面板的理想膜，因为它易于安装，完全不透水并且在混凝土桥面板，膜层和沥青覆盖层之间具有很高的粘结强度。这项研究的主要目的是为工业和运输机构提供对混凝土桥面板上沥青覆盖层破坏机理的更深入了解，并建立现场和实验室实验以评估这些覆盖层的性能。从这项研究的结果来看，推荐浇筑防水膜作为混凝土桥面板的理想膜，因为它易于安装，完全不透水并且在混凝土桥面板，膜层和沥青覆盖层之间具有很高的粘结强度。这项研究的主要目的是为工业和运输机构提供对混凝土桥面板上沥青覆盖层破坏机理的更深入了解，并建立现场和实验室实验以评估这些覆盖层的性能。从这项研究的结果来看，推荐浇筑防水膜作为混凝土桥面板的理想膜，因为它易于安装，完全不透水并且在混凝土桥面板，膜层和沥青覆盖层之间具有很高的粘结强度。
