PROBLEM TO BE SOLVED: To provide a percolation-type waterproof construction method for a concrete floor slab for a road bridge, which shortens a construction time, and which can form a waterproof layer with sufficient strength. SOLUTION: In this waterproof construction method for the concrete floor slab for the road bridge, a waterproof layer is formed on the concrete floor slab. The waterproof layer comprises a resin adhesive layer which is obtained by applying a resin adhesive onto the concrete floor slab for the road bridge and hardening the resin adhesive in the state of coating and impregnating the floor slab with the resin adhesive, and an asphalt coating film which is applied onto the resin adhesive layer and hardened. Characteristically, after the concrete floor slab is coated and impregnated with an epoxy resin adhesive with a viscosity of 2,500 mPa s/20°C or less as the resin adhesive, a heated asphalt waterproof material is applied onto an epoxy resin adhesive-coated surface which is formed by applying the epoxy resin adhesive onto the concrete floor slab, and the epoxy resin adhesive and the asphalt waterproof material are hardened.
