Abstract

Schotterzusammensetzung für ein Eisenbahn-Gleisbett, insbesondere für ein Gleisbett mit zumindest Anteilen aus aufgearbeitetem Altschotter mit folgenden Merkmalen:

  • die einzelnen Schottersteine besitzen mittlere Korndurchmesser zwischen 2 und 65 mm,
  • für die Kornverteilung gilt eine Ungleichförmigkeitszahl von U = d60/d10 ≥ 3 nach DIN 1080 in Verbindung mit DIN 18123,
  • die Kornverteilung weist keine Ausfallkörnung auf, das heißt die Kornverteilungslinie verläuft annähernd stetig,
  • das Schotterbett besitzt einen Wasserdurchlässigkeitsbeiwert von k ≥ 1 x 10-2m/s.
Ballast composition for a railway track bed, in particular for a track bed with at least portions of refurbished old ballast with the following features:
  • the individual gravel stones have average grain diameters between 2 and 65 mm,
  • a non-uniformity number of U = d 60 / d 10 ≥ 3 according to DIN 1080 in connection with DIN 18123 applies to the grain distribution,
  • the grain size distribution does not have any grain size, i.e. the grain size distribution line runs almost continuously,
  • the ballast bed has a water permeability coefficient of k ≥ 1 x 10 -2 m / s.

Ein Gleisbett mit einer Schotterzusammensetzung der vorgenannten Art besitzt innerhalb des Schotters hohe Dichten und eine insgesamt hohe dynamische Stabilität.
