Title of the articleAprobation of existing methods for assessing the wear resistance of crushed stone by the example of stone materials used in the Republic of Tatarstan
Abstract.Problem statement. The purpose of this study is to review various methods for assessing the wear resistance of stone materials that exist today and are used in road construction. At the same time, it is necessary to assess the wear resistance of materials used by local road-building organizations in the Republic of Tatarstan. Results. An analysis of the main methods for studying the wear resistance of crushed stone: Micro-Deval, Nordic test and shelf drum – showed the relationship between the Micro-Deval and Nordic test methods. The dependence of the wear indicator on the genesis of the rocks was revealed. Obtained data on wear indicators using these methods for stone materials of various quarries and rocks used by local organizations in the Republic of Tatarstan. Conclusion. The significance of the results obtained for the construction industry consists in the possibility to navigate when choosing stone material for the construction of road coatings. Evaluation of existing methods for assessing the wear resistance of crushed stone will simplify the survey and will help in further regulatory regulation of this issue.
Keywords.aggregates, abrasion resistance, roads, Nordic test, Micro-Deval, shelf drum.
