By Using polymer modified asphalt bridge deck waterproof coating synchronous shearing spraying technology, the fiber reinforced bridge deck waterproofing adhesive layer had succeed carried out in Xisang highway bridge. Shear test was conducted in the waterproof layer structure. When completed bridge deck pavement, core was drilled and samples were carried out pull-out test. The results indicate that fiber reinforced bridge deck waterproof layer can improve waterproof coating gave resistance, crack resistance and tensile ability. The introduction of asphalt bridge deck waterproof can improve the bonding strength between the layers and the overall shear strength of the waterproof layer, enhance the overall waterproof effect and enhance the service life of asphalt layer effectively.
