Research On Epoxy Asphalt Waterproof And Adhesive Layer Of The Concrete Bridge

The waterproof and adhesive layer is an important part of bridge deck pavement.The bridge deck diseases of Asphalt concrete,especially the early damages,indicate a fact that it is important to set the waterproof and adhesive layer in pavement structure.Nowadays in China,little studies on this topic is made,many bridge decks have diseased caused by the deterioration of waterproof and adhesive layer.So it has great theoretical and practical affection to study and analyze the layer in views of material and experiment.In this theme,based on epoxy asphalt material,systematically expatiating and analyzing physical chemistry characteristic and solidify characterstic of epoxy asphalt from adhesive point of view.In allution to concrete,this dissertation discusses in detail the stress of pavement and analyzes material and interface affect factor according to conglutinate intensity from epoxy asphalt.Adopting flexibility layer theory and the finite element mechanics method,the concrete and steel deck bridge are caculated by numerical value simulating.Then epoxy asphalt waterproof and adhesive layer are experimented by using sheer tests and other tests,validating the result of theorial analysis and numerical calculation,advancing the important mechanics index.Based on experimental project of The NanJing Third Yangtzi River Bridge, researching the real project about waterproof adhesive layer of epoxy asphalt and summarizing the problem that may happen in application, introducing measure of controlling and safeguarding qualitication.
