註釋The vibrations of railway track occur because of extreme impact load conditions due to the train operations with either wheel or rail irregularity. The vibrations result in track deterioration and severe environmental influences. Therefore, an urgent need exists to manufacture a sleeper/tie to mitigate these effects. This study used a fullscale model with different kinds of sleepers to measure the vibration mitigation attributes and dynamic characteristics of recently recycled rubber composite sleepers (RCSs) when applied to ballasted railway tracks and compared them with well-established concrete sleepers (CSs). A high-capacity drop hammer weight impact test was used to achieve this purpose, and the vibration effects on the track structural elements were analyzed. Two cases and a series of interaction force height (IFHs) impacts for both sleepers were applied.
