Mechanism Analysis of Concrete Bridge Deck Disease and Study on Composite Pavement Structure

Aimed at the experimental study about concrete bridge deck and the results analyzed by FEM methods,this paper expatiates the destroying mechanism of concrete bridge deck pavement and brings forward its designing criterion.This article also discusses the stress redistributing influence in different layers of bridge structure,which was caused by the difference of elastic modulus between asphalt concrete overlay and concrete bridge structure,and the design model of concrete bridge composite pavement structure.
