Low-strength Stabilization Method for Reducing of Settlement in Fouled Ballast
Year: 2025
Type: article
Abstract: As ballast on railway tracks is compacted and fragmented, settlement of the track tends to occur even after tamping, which leads to a need for more frequent maintenance. The basic measure to reduce maintenance frequency of replacing old ballast with new ballast, is costly. This calls for a low-cost method to reduce ballast settlement without need for ballast replacement. Therefore, we developed a low-strength stabilization method for reducing settlement without replacing ballast. This study confirms the effectiveness of the developed method for reducing settlement through laboratory tests. We conducted field tests on a commercial line to verify the effectiveness of this method in reducing settlement.
