Abstract: A method of backfilling recycled aggregate for power transmission and distribution lines, using a thermal resistivity prediction formula, is disclosed. The disclosed method of backfilling recycled aggregate for power transmission and distribution lines, using a thermal resistivity prediction formula, comprises: a step of designing a cross section on which the power transmission and distribution lines are installed, a step of selecting and transferring recycled aggregate to a construction site, wherein the recycled aggregate, which satisfies the quality standards of a road sub-base, is used to backfill the transmission and distribution lines; a step of excavating an area for installing the power transmission and distribution lines and of installing the power transmission and distribution lines; a step of backfilling recycled aggregate in the area excavated for the power transmission and distribution lines, of spraying water onto the area, and of hardening the area; a step of producing thermal resistance values using a thermal resistivity prediction formula after measuring the water content by weight and the on-site dry unit weight based on a part of the compacted recycled aggregate; a step of checking the relative degree of compactness of the recycled aggregate according to the burial depth using the on-site dry unit weight of the recycled aggregate and the indoor maximum dry unit weight; and a step of judging whether the heat resistance value is larger than the reference value or not or whether the relative degree of compactness is satisfied or not, and of spraying additional water more than the minimum water content by weight until the heat resistance value becomes under a reference value and the relative degree of compactness is satisfied in case the heat resistance value is larger than the reference value or the relative degree of compactness is not satisfied; or a subsequent step is taken in case the heat resistance value is less than the reference value and the relative degree of compactness is not satisfied.
