摘　　要：防水粘结层是桥面铺装体系的重要功能层,对于保证铺装体系路用性能起着关键作用。试验立足于提高防水粘结层的施工性能和路用性能,从材料、结构、作用理念等方面进行了优化,提出了橡胶沥青结构性防水粘结层,并结合试验路对其综合性能进行了评价,表明其能消除层间的水损害作用,抗施工损伤性能、粘结性能、抗剪切性能良好,并提出了橡胶沥青结构性防水粘结层的桥面处理要求。Waterproofing structural layer is very important in the concrete bridge deck paving.In this paper, a new waterproof material called asphalt rubber strucrural wateproof is provided to improve the performance and construction quality of the deck paving, and is analyzed from the waterproofing concept and structureanalysis. The performance of asphalt rubber structural waterproof layer is verified by the trial, which construction quality, adhesive property, shear retardant property is much good than usual, at the same time, this new waterproof structure is helpful to reduce the water in the layer. The quality control is provided for the asphalt rubber structural waterproof construction at the end.
