Study On The Synchronous Pavement Surface As Waterproof And Cohesive Of Concrete Bridge

This article according the introduction of disease condition of concrete bridge deck,references the condition of our country and foreign countries,bing that the analysis of problem of waterproof bonding layer, Suggest the new waterproof and cohesive of bridge------synchronous pavement surface.Firstly, this paper introduce the working principle of asynchronous pavement surface,andthe working principle of synchronous pavement surface------asphalt cement and aggregatesimultaneously pave and spread ,combine in a second .On the basis of analysis for working principle,Suggest that the advantage and the possibility of synchronous pavement surface as the waterproof bonding layer of bridge,as well as discussed the technical index of asphalt cement and aggregate.According the shear test and pull-out test , analyse the anti-shear strength and anti-pull-out strength,and contrast with common waterproof material. According the test,conclude the quantity of asphalt cement and aggregate.Based on the calculation and analysis,the change of shearing stress is obtained.Finally,the article also discusses the technology construction of bridge deck overlays,this can be the reference of construction course.The research result will even play an active role to generalize the synchronous pavement surface in whole country.
