Material Design of Bridge Pavement

Ding Qinjun Wang Fazhou Huang Shaolong Hu Shuguang\ Lu Zhe′anAssoc.Prof.,School of Materials Science,WUT,Wuhan 430070,China.  
In order to prove the damaging reasons of the bridge pavements and guide the material design, the structure mechanical analysis method was used through laying the stress pieces into bridge panels. It is shown that the poor bending flexibility and low adhesive strength between the pre laid concrete and newly pavement are the main reasons of the damaging. At last, We design one kind of newly material with steel fiber and polymer as well as early strength mixture and apply this kind of material to engineering. The repairing effect is good.
