Antivibration tests
on track segment

Characterization tests of the anti-vibration
performance of concrete sleepers with elastomer coating for ballastless applications,
carried out on track segments

The ”Grand Paris” Project involves a type of special concrete sleepers with integrated elastomer for Ballastless track system designed to mitigate vibrations depending on the installation site. Margaritelli Ferroviaria, compliant with the Technical Specifications, developed this new application on three different models of sleepers, one for each level of vibration mitigation required.

To characterize each model, tests on real conditions were performed by building three track segments 10 m long and a rigid reference track. The test procedure, inspired by DIN SPEC 45673-3, consists in measuring the system vibration response to an impluse applied to the rail at a known distance. During the test are also applied to the rails two loads representative of the suspended and not suspended masses of the rolling stocks. The results obtained for each track segment, compared with the rigid system, determine the Anti-Vibration performance of the three systems
