Selection And Application Of Waterproof Adhesive Layer For Cement Concrete Bridge Deck

Bridge construction is an important part of road development,the deck waterproofing adhesive layer is a bridge design and construction focus and difficulty.Although domestic and foreign waterproof adhesive layer on deck are a lot of research,but still lacks a unified scientific technical specifications and design specifications,and waterproof adhesive material are jumbled,resulting in the bridge due to the waterproof adhesive layer produces a lot of disease problems,affect driving safety and bridge durability.With the development of society and transportation,more and more cement concrete bridges are being built.Bridge deck waterproof adhesive layer is an very important factor affecting the durability of bridge structure and pavement.It is necessary to select appropriate waterproof adhesive layer material according to the type of bridge structure,engineering environment,traffic conditions,design safety level and so on in the area.At the same time,scientific construction scheme and construction technology should be selected to ensure waterproof adhesive layer.The durability of the bridge is enhanced by the performance of the bond material.In this paper,through combing the typical failure forms of cement concrete bridge deck structure and pavement due to waterproof bonding layer,synthesizing the needs of construction and maintenance at this stage,selecting a more suitable waterproof bonding layer material system,analyzing and studying its road performance,and bonding 108 National Road(Lujiatan-Nancun)The application experience of the entity engineering of the rebuilding project is summarized,studing its construction technology,and the application technology of the waterproof bonding layer of the cement concrete bridge deck is formed to guide the subsequent engineering application.The content of this paper provides some reference and reference for the selection and application of waterproof and cohesive layer on bridge deck.
