STUDY ON THE EFFECT OF INSERTION OF TRAIN ROLLING SUPPRESSION EFFECT OF ELASTIC AND PRESTRESSED CONCRETE SLEEPERS LAYING

Abstract

 Seven times of standard value excess occurs in 2019 on inspections of shaking of a vehicle. The main repair method is overall tamping of ballast when it is exceeded. However, this is not a good repair method because the standard value excess is tend to be occurred soon after repair work again at the same place. In this paper, we tested the hypothesis that sleeper replacement from a prestressed concrete sleeper to that with elastic rubber materials makes rail track better and decreases the number of the standard value excess of the inspections. As a result, we found that sleepers with elastic rubber materials are effective to suppress shaking of a vehicle and reduce maintenance cost in long term.
