الوصف: During the operation of asphalt concrete mix coatings in conditions of alternating temperatures, the formation of seasonal plastic deformations is often observed, expressed in the formation of ruts, waves and surges that violate the evenness of the upper layers of the road surface and temperature cracks that contribute to premature chipping and destruction of the coating. Such surface defects are primarily due to the specific properties of the organic binder used in the industry, expressed in the dependence of its rheological and physico-mechanical parameters on the ambient temperature. An alternative method that synthesizes both an increase in the working temperature range of the binder and the heat and crack resistance of asphalt concrete can be the use of alternative dispersed materials that serve as an active structuring filler in the technology of preparing asphalt concrete mixtures. In the present work, a series of mineral powders was considered: limestone, perlite, zeolite and expanded clay. The indicated powders differ from the classic limestone powder by their increased porosity and developed specific surface area. The study of the properties of asphalt binders prepared on the basis of various methods for the selection of bitumen confirmed that in the case of using porous mineral powders, it is most appropriate to take the indicator of water saturation, rather than residual porosity, as the criterion of optimal composition. In order to justify the prospects of using the studied powders for the preparation of organomineral composites, the quality level of asphalt binders was calculated. In accordance with the calculations, the quality level for water resistance was 1.29 for limestone, 1.21 for perlite, 1.23 for expanded clay, and 1.31 for zeolite. The results obtained allow us to judge the dependence of the quality level of the asphalt binder on the filler used, and indicate the feasibility of further research of dispersed mineral powders from perlite and zeolite.
