Development of Solid Bed Track on Asphalt Pavement

In general, ballasted track needs periodical track maintenance work, because ballast bed is gradually destroyed by repeated trainloads. Enormous expenditure is therefore necessary to maintain track in good conditions. In addition, it is increasingly getting difficult to obtain maintenance workforce, 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, a low-noise solid-bed track on asphalt pavement for new railway lines was developed to reduce the maintenance work. This paper describes the track structure, the results of the performance tests of this track and basic design.

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.
