Abstract
Ballast flow may occur at the place where displacement of roadbeds is large in curve. Ballast flow cause deformation of ballast shape and deterioration of lateral ballast resistant force, therefore maintenance work must be carried out frequently in that place. To control ballast flow, a method to restrict movement of the ballast around edge of sleeper with geosynthetic bags was examined. This method was evaluated by compulsion vibration test which used real scale track model on the imitation soft roadbed. As a result, ballast flow occurred at the resonance frequency in case of the normal track, however, ballast flow didn't occur in case of the track reinforced with geosynthetic bags.
