Bonding Between The Asphalt Pavement And Bridge Deck Layer To Improve The Technical Studies

Because of property of bridge deck pavement structure and environment where it locates, bridge deck overlay will causes to be destructed easily. Especially, spligage, one of the diseases,which was created between the bridge deck and asphalt pavement layer, is most serious. This paper, referring to the domestic and foreign related experiences, will introduce the technical theory of exposed-aggregate cement pavement into the bridge deck pavement creatively,and advance a new structure of bridge deck pavement.Through the appraisal index of shear strength,this article has carried on re search of influence regular of stablility of different interface structure type and waterprooft material through the indoor experiment;we have studied the regularof performance influenced by contact condition of layers also,and have design ed the fatigue test method between layers.Mechanics analysis and calculation ofdifferent contact surface form are carried on in this article by ANSYS finite element software.The test and theoretical analysis indicated that.exposed-aggrega te bridge deck pavement structure can enhance the capability of stablility betwe en layers largely, and can improve the road performance of bridge deck pave ment and prolong the service life of it.
