CONSTITUTION: A method for processing permeation water of a bridge surface(10') comprises steps of forming a concrete slab(20), executing level measurement of the top surface of the concrete slab and boring holes in the lowest right and left points to form drainage holes(30); fitting a PVC-pipe into the drainage holes and executing grouting or urethane waterproofing on the outer peripheral surface of the pipe, to form a drain pipe(40); installing two metal nets(50) in the width of the bridge to make the drainage holes covered; spreading a waterproof liquid on the concrete slab while preventing the metal nets from moving in paving the bridge surface on the metal nets; and paving the bridge surface with common asphalt concrete.
