Bridge waterproof structure and construction method thereof

The invention discloses a bridge waterproof structure and a construction method thereof, and relates to the technical field of bridges. The asphalt layer is arranged above the concrete layer; the waterproof structure is arranged between the concrete layer and the asphalt layer and comprises a base treating agent layer, a carcass reinforced fiber layer, a hot-melt rubber asphalt layer and a gravel layer which are sequentially arranged in the direction from the concrete layer to the asphalt layer; and the base layer treating agent layer is used for bonding the carcass reinforced fiber layer and the concrete layer. The failure possibility of the waterproof structure can be reduced. 本发明公开了一种桥梁防水结构及其施工方法，其涉及桥梁技术领域，桥梁防水结构包括：混凝土层；设置在所述混凝土层上方的沥青层；设置在所述混凝土层和沥青层之间的防水结构，所述防水结构包括：自所述混凝土层向所述沥青层方向依次设置的基层处理剂层、胎体增强纤维层、热熔橡胶沥青层和碎石层，所述基层处理剂层用于粘接所述胎体增强纤维层和所述混凝土层。本申请能够降低防水结构出现失效的可能性。
