Bridge pavement maintenance construction method

The invention relates to the technical field of road maintenance, in particular to a bridge pavement maintenance construction method which comprises the following construction steps: S1, preparing the following materials in parts: 100-200 parts of polymer, 200-500 parts of asphalt, 10-300 parts of curing agent and 10-200 parts of water; s2, pouring the asphalt and the polymer into a reaction kettle, heating, and stirring; s3, adding a curing agent and water in the stirring process, and uniformly mixing to prepare polymer asphalt; and S4, heating the polymer asphalt, and paving the polymer asphalt at the positions with cracks and pits on the bridge pavement. Polymers of different materials are added into the asphalt material, the material property of asphalt can be greatly improved, the asphalt solidification speed is increased, the influence of external temperature on asphalt solidification is reduced, the asphalt solidification degree can be detected in real time, a warning board can be taken away in time, t
