Abstract: Disclosed are a prefabricated wire mesh assembly for a ballast and a method of constructing a gravel-ballasted track using the same. When a gravel ballast is used by filling a box-shaped rebar mesh with crushed stones and injecting a filling material, the prefabricated wire mesh assembly increases injection efficiency by further installing an internal partition wall to effectively support loads without forming a separate ballast shoulder and injecting a filling material through injection pipes installed on an internal partition wall, and prevents water accumulation on a roadbed by a drainage pipe. The prefabricated wire mesh assembly for a ballast is assembled by installing the injection pipe along with the lower mesh and the internal partition wall, thereby allowing the filling material to be injected without installation of a plurality of separate injection pipes, and securing construction quality by increasing injection efficiency of the filling material through the installed injection pipes.
