<P>PROBLEM TO BE SOLVED: To provide a repair method which allows a repair filler to have excellent adhesion to a concrete roadbed or a track slab, without the repair filler protruding outside, and prevents strength degradation of a track slab caused by hole drilling, with improved working efficiency. <P>SOLUTION: A repair method of a slab track includes a track slab 14 fixed to a concrete track roadbed 10 across cement asphalt mortar 18, and a track rail 20 held to the track slab 14. The method comprises the steps of: (a) forming a void having an opening along the outer periphery of the track slab 14 by removing deteriorated cement asphalt mortar 18 from the circumference of the track slab 14 to an appropriate depth in horizontal direction; (b) filling the void 30 with a bag 32 for repair from outside; and (c) injecting a repair filler 42 into the bag 32 for repair to inflate the bag 32 for repair, which comes in close contact with at least the top and bottom faces of the void 30 to be fixed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
