PROBLEM TO BE SOLVED: To improve construction efficiency by reducing or dispensing with replacement work of ballast by using a filling-up material excellent in fluidity.SOLUTION: In a construction method of a filling-up roadbed track for solidifying a ballast roadbed 3A by injecting a filling-up material 6 into a ballast track 10 in which a sleeper 4 and a rail 5 are laid on the ballast roadbed 3A in which all over ballast 3 is laid on a roadbed 2, the construction method of the filling-up roadbed track is provided with a process of taking out the ballast 3 positioned on both sides of the sleeper 4 among the ballast 3 along the arrangement direction of the sleeper 4, a process of arranging impervious sheets 7A and 7B in a state of making a lower end part 7a reach the roadbed 2 in an excavation groove of both side parts of the sleeper 4 from which the ballast 3 is taken out and a process of injecting the highly-fluid filling-up material 6 into the inside ballast 3 of the mutual impervious sheets 7A and 7B.SELECTED DRAWING: Figure 2
