In the slab track laid in a cold area, gaps are generated between the track slab and the filling layer. Currently, the gap is repaired based on the amount of gap measured. In the future, new repair criteria based on a characteristics of load resistant capacity of track slab will be required. Therefore, loading test of slab model specimens and finite element analysis of slab tracks were performed. Based on these results, a repair criteria using displacement of the track slab was proposed.
