PURPOSE: A polymer modified concrete composition for bridge deck pavement and a bridge-deck paving method using thereof are provided to increase construction speed by enabling mass production of concrete using ready-mixed concrete plant or a field batch plant. CONSTITUTION: A polymer modified concrete composition for bridge deck pavement comprises cement, aggregate, polymer emulsion, and water. The polymer emulsion includes at least one of polycarboxylic acid based surfactant for cement cohesion prevention or water-dispersible urethane based surfactant for cement cohesion prevention, and nonionic surfactant for cement cohesion prevention. The polymer emulsion comprises cement hydration retarder. A bridge-deck paving method comprises next steps: washing the surface of a bridge; manufacturing polymer reforming concrete composition in a ready-mixed concrete factory or a field batcher plant; transporting the reformed concrete composition to the bridge by using the ready-mixed concrete; installing the polymer modified concrete composition on surface of the bridge; and curing the polymer modified concrete composition.
