Deck Technical Performance Of Flexible Waterproof Material

Based on surveying the duration of concrete bridge, through analyzing the reasons and mechanism of causing disease, combined with the most new research at home and abroad, this paper brings forward the necessity and research approach of flexible waterproof material for concrete bridge decks. Because there are not the norms or specifications for the bridge deck waterproofing, the paper, from physics performance ~.. road performance and resisting construction performance, has mainly studied the methods and the corresponding evaluating indexes of the inside experimentation for the flexible waterproof material for the concrete bridge decks. At the same time, this paper has chose special waterproof material from lots of waterproof material of architecture type. In order to change the condition that the engineers lack help in design and construction, the paper has introduced the design theory and method for the waterproof system of bridge decks~ the construction technology for waterproofing system and the controlling system for construction quality. In the end, combined with the field experimentation research in real project, the paper has checked and improved the relevant contents.
