Test on Shear-Resistance of Waterproof and Cohesive Layer Materials in Concrete Bridge Deck

Bridge deck pavement diseases,especially the early damages are usually caused by the failure of waterproof and cohesive layer.Lack of shear-resistance will lead to shoving,folding,rut and other distresses.Thereby,basing on Study on Durable Asphalt Pavement Structure of Concrete Bridge,the program from Traffic Department of Zhejiang Province,this paper studies the shear- resistance of three different waterproof and cohesive layer materials:hot sprinkled SBS modified asphalt,cement-based waterproofing coating and pitch-based waterproofing coating in order to provide some references to future projects.
