Abstract

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.
