| Abstract: | Structure design scheme and the new steel deck pavement materials are brought forward.The scheme is that using high strength semi-lightweight concrete as the lower floor of the steel bridge deck pavement,by welding shear connectors and binding reinforcement mesh to improve the consistent distortion capability between pavement and steel deck.By optimizing the mix ratio of high strength semi-lightweight concrete,using fiber and polymers to improve toughness and strength,the distortion capability and durability of concrete are improved.These measures improve the using life of steel deck pavement. |
