초록
Ballasted track is constructed in consideration of the maintenance. The application time and frequency of MTT(Multiple Tie Tamper) and BS(Ballast Cleaner) depend on track geometry measurements. This paper presents the application of Ground Penetrating Radar(GPR), Falling Weight Deflectometer(FWD), and Portable Ballast Sampler (PBS) to evaluate the effects of track geometry due to substructure deterioration and to build a reliable substructure evaluation system.
