PROBLEM TO BE SOLVED: To propose a technique for accomplishing a ballast track which is installed or maintained more easily, while keeping the merit that the ballast track has as it is, and further to make the merit of the ballast track available even for any other purpose than track construction.SOLUTION: A ballast body 4 of a ballast or the like is compacted into a die 6 and a point contact structure of ballast in a ballast track is accomplished. A ballast body aggregate block 2 is then created which maintains the point contact structure by integrally molding the ballast bodies while applying a joint material 8 thereto. By disposing the ballast body aggregate blocks 2, the ballast track can be laid easily. Furthermore, since the ballast bodies 4 are coupled integrally, the problem of stone chipping or the like does not occur, either and since the point contact structure is maintained, maintenance is reduced in comparison with the conventional ballast track. Moreover, by disposing the blocks, low-vibration/low-noise properties of the ballast track can be utilized at any arbitrary place. |
