WATERPROOF METHOD FOR PAVEMENT

摘要

A waterproofing method for pavement of a road according to the present invention comprises: an improved asphalt preparing step of putting improved asphalt into a container which can be heated to prepare the improved asphalt; a resin preparing step of putting epoxy resin into a container which can be heated to prepare the epoxy resin; a heating step of heating the improved asphalt and the epoxy resin; and a waterproof layer forming step of feeding the heated improved asphalt and the heated epoxy resin to a spraying device (40) via different nozzles (50), crossing the improved asphalt and the epoxy resin at a ratio of 5.5-6.5 to 3.5-4.5 in a spraying hole of the spraying device (40) to mix and spray the improved asphalt and the epoxy resin onto the upper surface of a bottom layer (10), paved with asphalt concrete, for forming a waterproof layer (20). Then, the present invention further includes: an asphalt concrete placing step of placing the asphalt concrete on the upper surface of the waterproof layer (20) to form an asphalt concrete layer (30); and a curing step of curing the waterproof layer (20), paved in a liquid phase at room temperature, by the heat of the asphalt concrete layer (30) formed on the upper surface of the waterproof layer (20). The waterproofing method for pavement of the road according to the present invention can maximize an interlayer coupling force between the bottom layer, the waterproof layer and the asphalt concrete layer. In addition, the present invention can make the waterproof layer play roles of a tack coat and a primer coat simultaneously to simplify the conventional three step procedure for forming a waterproof layer, a tack coat layer and a primer coat layer, thereby reducing period for asphalt pavement construction and saving construction costs.
