“…It was mentioned that experimental data obtained that the maximum decrease of the resulting oscillation amplitudes is observed where polyurethane mats are installed (Ld = 2.47) while porous rubber mats show Ld = 1.75. 39,60 A kind of UBM made of recycled rubber showed a 50% reduction in the impact-induced stress. 61 Besides, laboratory tests and numerical studies on ballasted ladder tracks with UBM revealed that the combination of a ballasted ladder track and UBM with a stiffness of 0.06 N/mm3, attenuate vibration better (between 30-100 Hz), but greater vibration was seen below 30 Hz.…”

A high frequency of loadings and an excessive amount of axle loads are rising as trains are becoming faster and heavier. In this regard, improvements in track design, such as using an under ballast mat, are vital to performance improvement. In addition to reducing noise, vibration, and ballast degradation, UBMs are designed to improve the dynamic behavior of tracks, thus extending their service life and increasing safety. This paper provides an overview of the recent developments on UBMs, identifies the crucial characteristics of different kinds of mats, including fatigue strength, environmental conditions, stiffness, and ballast deformation, and describes challenges for more widespread adoption. Limitations of using a UBM include their high cost and stiffness, limited knowledge of long-term efficiency, and interlocking reliability. This paper also provides future perspectives and prospects for overcoming the challenges in the utilization and acceptance of UBMs.

“…Static and dynamic bedding modulus determine effectiveness of dumping vibrations transmission to the environment [8,9,10,11,12,13,14]. It should be noted that the Under Sleeper Pads with very low value of bedding modulus give in greater sheer deflection of rail and railway track.…”

The paper describes the essential functional and operational features of the Under Sleeper Pads (USPs), used in ballasted rail track systems. The overview of appropriate test methods for determining the values of relevant parameters for the purposes of using vibro-acoustic isolators was presented, with special attention drown to the changes resulting from the introduction of the PN-EN 16730 standard in this field. Due to the given testing procedures for USPs, selected examples of the normative testing methods of the USPs’ carried out at the Faculty of Civil Engineering of the Warsaw University of Technology with the results were presented.

The paper presents an overview of vibroacoustic isolators used in railway tracks to reduce negative effects from railway traffic. These include single components or their assemblies, with different material characteristics and location in the track structure due to track structure type (ballasted or ballastless track system). The reduction of negative effects relates mainly to the reduction of vibration and structure-borne noise. The practical solutions for railway structures include various components that perform different functions at the same time: vibroacoustic isolation and mechanical function to ensure safe and durable use of rail track (i.e. rail fastening systems, rail supporting structures). The main goals of this paper are systematization and description of basic material characteristics of vibroacoustic isolators applied sufficiently close to the place of vibration generation during the movement of rail vehicles.
