Ballast mats Vibration Reduction

Ballast matsTrackelast Ballast Mats are designed to give the optimum static and dynamic properties for use with main line, urban, light rail and metro axle loads. Our Ballast Mats are one of the most eff ective methods of reducing vibration transmission from ballasted track.

Overall benefits include:

• Excellent reduction of ground-borne noise and vibrations• Stabile performance at low and high temperatures• High mechanical strength

We also provide the facility to pre-cut ballast mats to your requirements, in our factory which enables immediate installation on site. Installation is straightforward, and full fi tting instructions are supplied. A range of rubber formulations are available to give a wide range of stiff ness for diff erent conditions and applications.

When installed under ballast, Trackelast Ballast Mats isolate the track structure from the supporting foundation or substrate, which can result in attenuation levels in excess of 20dB. Trackelast Ballast Mats are proven to give reliable performance over a very long service life under any climatic conditions.

Our ballast mats comprise of a soft resilient layer, usually made from natural rubber because of its excellent dynamic properties. This layer is typically 8-30mm thick and is faced with an integral bonded geotextile felt type of ballast protection layer. Mats can be supplied with this protection layer on both sides to provide additional protection from sharp stones and gravel in the track-bed substrate.

Tifl ex make ballast mats in line with the specifi c requirements of railway authorities. This proscriptive approach designates the stiff ness of the ballast mats for diff ering axle loads, speeds and application

Specified design

All mats are supplied on pallets easily transported to site and can be laid by one or two persons very quickly. It is easy to cut the sheets to negotiate curves or access points in the track bed.

Flat profi le sheets

Please contact us with your requirements/drawings.

Our in-house design team, technical support and the fl exibility of our ISO9001 accredited manufacturing plant makes Trackelast the ideal supplier of your rail product requirements.

Specifi ed design or tailored-made performance design

We can also tailor make ballast mats to achieve specifi c 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.

All Trackelast ballast mats are supplied as fl at non profi led sheets, with the resilience being designed into the material by a combination of a microcellular structure and compressible cork particles. The use of fl at sheets eliminates the need to counteract drainage paths and dirt collection points under the mat which could infl uence the long term attenuation levels.

At Tifl ex, we don’t just manufacture large quantities of ballast mats. Where smaller quantities of ballast mats are required for transition zone of turnouts and crossovers we can provide these too. For some installations it is necessary to put ballast mats on the side walls, these may be thinner and stiff er than those on the base of the channel. These vertical mats are sometimes pinned or glued to the side walls. Tifl ex will assist you in choosing the correct product for whatever the task is.
