NOVELTY - Manufacturing bridge deck waterproof material involves: (1) preparing a bottom waterproof layer by mixing chloroprene rubber, polyisobutylene, quartz sand, calcium carbonate and nanofibers, adding to a reaction kettle, heating and stirring; (2) preparing a middle waterproof layer by mixing neoprene, polyurethane, acrylic emulsion, polyisobutylene, calcium stearate and anti-aging agent, adding to the kettle, stirring, then taking out, and refining using an open mill; (3) preparing a surface waterproof layer by mixing ethylene-propylene-diene monomer rubber, acrylic emulsion, nano graphene, nano silicon dioxide sand and asphalt, adding to the reaction kettle, heating, stirring, and refining using the open mill; and (4) laminating, rolling and rewinding by adhering asbestos fiber nets on upper and lower sides of the middle waterproof layer, then bonding together the bottom and surface waterproof layers, rolling by a hot rolling mill, treating the surface with talc powder, and rewinding. USE - The method is useful for manufacturing bridge deck waterproof material. ADVANTAGE - The method provides bridge deck waterproof material with excellent ductility and tensile strength, and avoids the layering of the asphalt and the underlying pavement by adding the asphalt component to the waterproof layer of the bottom and surface layers. When the asphalt on the bridge deck cracks, the waterproof material can stretch without breaking, which increases the waterproof performance of the material.
