Large volumes of elastomers are coming into use in the track structure. The so-called Ballast Mat, which is an example of elastomer applications, is intended to serve as support for crushed stone ballast in the ballasted track structure on the elevated railway. It is expected to be effective for mitigating noise and vibration as well as preventing development of heavy wheel load and deterioration of crushed stone under train speedup. Tests have been started to check the anti-vibration, anti-noise effects of prefabricated vulcanized rubber mats as attached to the bottom of concrete slabs in the ballastless slab track. Meanwhile, elastomers of another new type with various compositions using room temperature-vulcanized polyurethane rubber as the base have come to be introduced in versatile applications such as gap-adjusting fillers for the ballastless slab track and the ballastless wooden-tie track.
