RBPC Steel Bridge Deck Paving Technology Based on Shear Free Nail System and its Application
In order to explore new technologies for the full life cycle maintenance of the steel bridge deck of the Long Bridge and solve the problems of existing steel bridge deck pavement and orthogonal anisotropic plate fatigue damage,carries out the research of resin connect-ed ultra-high performance concrete RBPC paving technology.The research results show that compared with epoxy type EA pavement structures under the same conditions,RBPC pavement reduces steel plate stress by about 40%and increases the stiffness of the steel bridge deck structure by more than 50%,verifying that this pavement structure has a certain stiffness improvement and reinforcement effect on orthotropic plates;The new process of using a slow bonding wet adhesive instead of a bolt bonding waterproof and anti-skid lay-er(RBChip)changes the contact method from"point"to"surface",which is convenient for later maintenance and repair.It has also been successfully applied for the first time in the pavement reset project of the Yangtze River Highway Bridge in China.
