NOVELTY - Waterproof coiled material comprises lower isolation layer, lower modified asphalt layer, reinforcing tire base layer, upper modified asphalt layer and upper isolation layer arranged in sequence. The raw materials of the lower modified asphalt layer and the upper modified asphalt layer are the same comprising 40-60 pts. wt. asphalt, 5-15 pts. wt. styrene-butadiene-styrene elastomer, 5-10 pts. wt. modifier, 10-20 pts. wt. solvent oil, 10-20 pts. wt. filler, 2.-9.5 pts. wt. flame retardant and 0.1-0.5 pts. wt. low temperature resistant auxiliary agent. USE - The waterproof coiled material is useful in the waterproof system of railway bridge concrete deck or ballasted track (all claimed). ADVANTAGE - The waterproof coiled material has excellent high and low temperature resistance, good bonding force, durability, good physical mechanical property and aging resistance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Preparing waterproof coiled material, comprising (i) preparing raw materials according to the ratio, preheating the asphalt to 150-180℃, adding the styrene-butadiene-styrene elastomer, modifier and solvent oil in turn, and stirring at a slow speed at 170-180℃ for 3-4 hours, adding the filler, flame retardant and low-temperature resistance additive in sequence into the mixture obtained, maintaining warmness and stirring continuously at a slow speed for 3-4 hours to obtain modified asphalt; (ii) soaking the reinforced tire base in the modified asphalt for 1-2 hours, taking it out, flattening it and cooling it to obtain the modified asphalt and reinforced tire base composite material; (iii) using the modified asphalt obtained in step III and one side surface of the reinforced tire base composite material carry out the following operations comprising spraying fine sand and/or stone powder until the fine sand and/or stone powder cover 50-80% of the surface or (b) paving said adhesive and applying geotextile or polyethylene film on the other side to obtain waterproof coiled material; and (iv) rolling the lower isolation layer of the modified asphalt waterproofing coiled material that step III outwards and packing, preferably, in the step (i) the stirring speed of slow stirring is 50-200 revolutions/minute; and Application of waterproof coiled material in the waterproof system of railway bridge concrete deck or ballasted track, comprising (a) removing dust, decontaminating, leveling and drying of the concrete base; (b) removing the lower isolation layer of the modified asphalt waterproof coiled material and exposing the lower modified asphalt layer; (c) fixing the modified asphalt waterproof membrane on the concrete base by the following method by heating and baking the modified asphalt layer under the modified asphalt coil to a softened state with an open flame, and pressing the coil while baking, so that the coil and the concrete base surface are fully bonded or spraying thermal adhesive paint on the surface of the lower modified asphalt layer, and spreading it while spraying, so that the coiled material and the concrete base surface are fully bonded or spraying or smear the adhesive on the surface of the lower modified asphalt layer, and lay it while spraying or smearing, so that the coil and the concrete base surface are fully bonded; and (d) paving of the modified asphalt waterproof coiled material, pouring the concrete mixed on site onto the surface of the modified asphalt waterproof material, vibrating and maintaining.
