According to the present invention, after a vinyl material is crushed into the predetermined size and is mixed in an asphalt binder in the predetermined weight rate, an asphalt concrete structure under a paved track for railroad is formed by heating the mixed mixture at a temperature of 160 to 170°C. According to the present invention, the asphalt concrete structure (300) under a paved track for railroad lowers the sensitivity to temperature of an asphalt binder itself and improves the viscosity of the asphalt binder. The present invention can reduce the damage that a work is burned at the time of the construction of asphalt mixture and can reduce the plastic settlement due to the sudden increase of temperature in the summer time by improving the sensitivity to temperature of the asphalt itself. The prevent invention can prevent the asphalt from being suddenly contracted and damaged due to the cold atmospheric temperature in the winter time, and can extend the service life and durability of the pavement by improving the viscosity of asphalt and coupling the asphalt binder to aggregate, such as rubble.
