Application of Fiber Reinforced Waterproof Technology in Xisang Highway Bridge Deck Waterproof Layer

摘要

The fiber reinforced bridge deck waterproofing adhesive layer (FRBDWAL) was set in Xisang Highway Bridge through using polymer modified asphalt bridge deck waterproof coating synchronous shearing spraying technology. Shear test was conducted in the waterproof layer structure. After bridge deck pavement was built, core was drilled and pull-out test was carried out. The results indicate that fiber reinforced bridge deck waterproof layer can improve cracking resistance and tensile performance of waterproof coating. It can also enhance the bonding strength between the layers and the overall shear strength of the waterproof layer, which can also augment the overall waterproof effect and the service life of asphalt layer effectively.
