“…The review results also suggest that the mineral composition, structure, and size of mineral components definitely have a significant influence on the resistance to wear and fragmentation. Interestingly, the majority of publications related to research into aggregate wear and fragmentation resistance tests address issues of mutual relationships and correlations between aggregate properties [ 3 , 11 , 14 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 ].…”

The aim of this article is to present the current knowledge and experiences related to wear and fragmentation resistance tests and to indicate those of their aspects that require further research. For this purpose, a review of the literature was performed. Results show that tests of resistance to wear (the MDE/DS test) and fragmentation (the LA test) are performed worldwide according to different standards (and thus following different test methods), which prevents a comparison of the obtained results. Comparative research into the MDE/DS and LA tests indicates that the MDE/DS test is more effective. The disadvantage of both tests lies in the dimension range of the aggregate. In addition, the use of steel balls in the LA test may not reflect the actual influence that the internal properties of the material have on the fragmentation process. A final review of the available knowledge allowed the formulation of proposals regarding further research directions, such as proposed changes of test methods, extensive analysis, and selection of optimal dimensions for tested aggregates, analysis of short-term and long-term tests, as well as extensive research into and an analysis of the impact of crushing on the physical, mechanical, and geometric properties of aggregates.

One of the main products of the mining industry is crushed stone, which is an essential material in structure construction, such as concrete aggregate, asphalt aggregate in road construction, ballast aggregate in railway construction, etc. Due to the application fields, evaluating the durability of these aggregates is required. An economical and durable design cannot be achieved without knowing the resisting capacity of the used stone materials to abrasion, crushing, impact, and disintegration – collectively known as mechanical weathering or degradation. In addition to presenting different forms of mechanical weathering of aggregates, the paper summarizes the most frequently used laboratory tests developed to determine the resistance to these stresses. It introduces various national standards emphasizing their differences and examines the possibility of test result comparability with respect to geology and practical application. The research also presents several empirical relations from the literature between the different degradation parameters. Besides that, the paper aims to give an overview of the international literature that deals with the mechanical weathering of aggregate materials by using organizing tables and comparative graphs; it tries to contribute to the organization and comparability of the existing knowledge and the results found in the literature.
