The results showed that the ballast mat has ability to mitigate train-induced environmental vibrations. The acceleration level can be highly reduced within 30 m from the track centerline on the ground. Increasing the thickness of the ballast mat and increasing the static foundation modulus can enhance the vibration mitigation effect.

Tiflex can also tailor make ballast mats to achieve specific performance requirements for the attenuation of vibration in environmentally sensitive areas, taking into account track bed and soil conditions, train operational loads and other local factors. Flat profile sheets.
The R 24 is a high-output ballast regulator on bogies, especially designed for the construction and maintenance of high speed lines. It is equipped with a 10m3 hopper, expandable to 13m3 which allows the excess ballast recovery and redistribution to the areas with low ballast density.
Vibration reduction effect of laying ballast mats under ballast tracks on bridge in environmental sensitive areas May 2017 Zhendong yu Chongji/Journal of Vibration and Shock 36(10):38-44
Ballast mat: Ballast mats are designed to be placed under ballast and tie track. However, some embedded track designs have used ballast mat under a concrete slab as a vibration mitigation measure. In essence, the ballast mat is used to create a floating slab. This approach has the advantage of putting a continuous layer under
Ballast Mats Mass-Spring-Systems Tie Pads – Given dynamic rail deflection during train passage Adjustment of the overall track stiffness using sleeper pads, baseplate pads, rail pads or ballast mats with designed stiffness – Long term settlement of the track
Tiantie Track Mats are one of the most effective methods of reducing vibration transmission from ballasted or slab track. When installed under ballast, Ballast Mats isolate the track structure from the supporting foundation or substrate, and can attenuate the vibration transmission by 20 dB in many cases.
Apr 29, 2016· • Dustbin and ballast fines were drifted away, especially for the 200-250km/h exited HSR, and delusion of so-called ballast flight. China speed up experience. • Solutions: • Fresh ballast add-in and undercutting. • Prevent the foreign particle intrusion into ballast, such as cover or glue coated coal car, and train toilet updated.
