The resistance of aggregates to abrasion estimated by the Micro‐Deval test is an important mechanical parameter for aggregates used as railway ballast. At present, testing intervals are sparse due to the cost of the tests. Cost‐efficient testing methods would be greatly appreciated. A detailed study of the applicability of alternative testing methods, as commonly used to estimate the potential of a rock or soil to cause wear to a tool (LCPC Abroy test and Cerchar test), demonstrates the advantage of implementing these testing methods in addition to the recommended tests.
