IMPROVED SEATINGS FOR BALLASTED TRACKS

VERBESSERUNG DES SCHOTTEROBERBAUS IN TUNNELN UND AUF BRUECKEN MIT ELASTISCHEN POLYURETHAN-MATTEN

When the track ballasting is laid on a hard surface this not only produces higher stressing, but also increases the level of sound transmission. The problem is particularly acute in tunnels and on bridges carrying high-speed traffic. The fitting of flexible mats--especially SYLOMER matting--has an ameliorative effect as follows: deadening of solid-borne noise on underground railways (passing below built-up areas), reduced noise reflection from steel bridges, reduced dynamic stressing of the ballast, especially at high speeds, retention of the correct track level for considerably longer periods in tunnels and on bridges, reduced maintenance costs. The article describes the properties of the matting and various laboratory and practical test results.
