Bridge deck pavement material, preparation method and pavement method thereof
The invention provides a bridge deck pavement material as well as a preparation method and a pavement method thereof. The bridge deck pavement material comprises a first additive, a second additive, a filler and modified asphalt, the mass ratio of the filler to the modified asphalt is (15-45): (36-90); the first additive is a carbonized porous polymer, the ratio of the content of the first additive to the total mass is X, the ratio of the content of the second additive to the total mass is Y, and X and Y meet the following relational expression: 1.2 X < = X + Y < = 5X; 1.4 Y < = X + Y < = 3Y; according to the paving method, the content of heat-conducting fiber powder of paving materials from the lowest paving layer to the topmost paving layer is controlled to be gradually reduced in sequence, and the content of rubber particles and polymer materials of the paving materials from the lowest paving layer to the topmost paving layer is controlled to be gradually increased in sequence. The bridge deck pavement material and the pavement method thereof provided by the invention have relatively high water stability, high-temperature-resistant stability and low-temperature crack resistance.
本申请提供一种桥面铺装材料、制备方法及其铺装方法，桥面铺装材料包括：第一添加剂、第二添加剂、填料和改性沥青；所述填料和所述改性沥青的质量比为(15～45)：(36～90)；所述第一添加剂为碳化的多孔聚合物，所述第一添加剂的含量占总质量的比值为X，所述第二添加剂的含量占总质量的比值为Y，所述X与Y满足以下关系式：1.2X≤X+Y≤5X；1.4Y≤X+Y≤3Y；通过控制最低铺设层至最顶铺设层中铺装材料的导热纤维粉的含量呈依次递减，控制最低铺设层至最顶铺设层中铺装材料的橡胶颗粒和聚合物物料含量呈依次递增的铺装方法；本申请提供的桥面铺装材料及其铺装方法，具有较高的水稳定性，耐高温稳定性和低温抗裂性。
