Settlement Restoration for Concrete Track on Operating Line

초록

Various design factors should be considered in order to apply the concrete track system on earthwork. The most important factor is the settlement control. The settlement of concrete track should be sustained within the allowable settlement limit. If settlements of roadbed under the concrete track exceed the allowable limit, the track will be seriously deteriorated. Therefore, it is need to prepare a appropriate countermeasure before the commercial operating. In this paper, we introduced a pressurized rapid-hardening cement grouting (PRCG) method as a settlement restoration method that can be adopted to the concrete track.
