Development and Practical Use of Paved Track for Revenue Line

In recent years, the destructive force acting on the ballasted track is on the increase with the speed-up of trains and the increase in the number of trains, requiring more labor and expenditure to maintain the track in good condition. On the other hand, it is increasingly difficult to obtain maintenance manpower, because Japan is quickly shifting to a society of elders, and people tend to hate tough works such as manual track maintenance work. Under these circumstances, the Paved Track which is to be laid during the midnight interval on existing line has been developed and improved in order to reduce the maintenance work of the ballasted track on subgrade. This paper describes the track structure and the results of the performance tests of this track.
