Abstract

Der mittels des Mikro-Deval-Tests ermittelte Widerstand gegen Verschleiß ist ein wichtiger mechanischer Kennwert von Gesteinskörnungen, die als Bahnschotter Verwendung ﬁnden. Derzeit sind wegen der hohen Kosten für die Prüfungen große Prüﬁntervalle üblich. Wirtschaftlichere Testverfahren wären hochwillkommen. Eine umfangreiche Studie zur Anwendbarkeit von Prüfverfahren zur Abschätzung des Werkzeugverschleißes zufolge des Verschleißpotenzials von Boden oder Fels (LCPC Abroy-Test und Cerchar-Test) stellt die Vorteile des Einsatzes dieser Verfahren als Ergänzung zu den etablierten Prüfverfahren dar
