The present invention relates to a method for separating recycled aggregate using thermal shock and a system for separating recycled aggregate using thermal shock, wherein the method for separating recycled aggregate according to the present invention comprises a preparation step of preparing a recycled aggregate including a mother rock and a mortar, and the preparation step A heating step of heating the recycled aggregate prepared in the heating step, a cooling step of applying a thermal shock to the recycled aggregate by cooling the recycled aggregate heated in the heating step, and a flow of the recycled aggregate cooled in the cooling step to separate the mother rock and the mortar And a separation step, wherein the recycled aggregate separation system according to the present invention includes a heating unit that heats the recycled aggregate contained therein to a set temperature, and is connected to the heating unit, and transfers the recycled aggregate heated by the heating unit to a fluid of a set temperature. Including a cooling unit for cooling by immersion, a separation unit for separating the mother rock and mortar contained in the recycled aggregate by flowing the recycled aggregate cooled in the cooling unit, and a sorting unit for separating and storing the mother rock and mortar separated by the separation unit do. The separation method proceeding in the above order can increase the separation efficiency of the mother rock and the mortar by applying a secondary thermal shock, and has an economic advantage. In addition, the separation system having the above configuration has the advantage of being able to process a large amount of recycled aggregate and enabling an automated process.
