The invention relates to a technical method for paving road steel bridge decks by combined applications of various composite paving materials. The technical method comprises an adhesive layer, a coiled material and bulk materials. The technical method is characterized in that the adhesive layer, the coiled material and the bulk materials are paved and tamped successively and hierarchically, wherein the adhesive layer is a spraying coating which are waterproof and rustproof and has strong adhesion to the rigid bridge deck; the coiled material is a sheet and windable spread paving material which is formed by using inorganic, high-strength, low elastic knitted fabric as a support grid structure and polyurethane asphalt concrete as a filling material; and the bulk materials are modified asphalt concrete with much coarse aggregate, slag, asphalt and little fine aggregate. Compared with a conventional method, the technical method provided by the invention is characteristics of waterproof and anti-corrosion protection steel bridge deck, synergetic reinforced bridge deck rigidity, anti-extension, anti-shift and anti-breakage, difficult appearance of delamination, cracks, tracks and pushed piles, antifatigue, aging resistance and the like. Besides, the technical method has the advantages of strong industrial production adaptability, less materials, low cost, simple repair and maintenance, etc. Therefore, the technical method has very good prospects for popularization and applications.
