| Title of the article | Modern methods of assessment of operating ability of road asphalt concrete |
| Abstract. | Problem statement. To investigate road asphalt concrete on sites of the coverings having defects in the form of hollows, track, cracks of peeling. Results. The carried-out comparative analysis of components in asphalt concrete has shown what compositions of the applied bitumens are characterized by the increased maintenance of asfalten. It is also found that the structure of the breeds included in the major mineral aggregates of bituminous concrete has defects contain harmful impurities. The revealed deviations from requirements of normative documentation can influence the decrease in durability of asphalt concrete and its premature destruction. Conclusions. Modern inspection methods of operating ability of asphalt concrete have to rely on studying of component composition of bitumens and raw materials for its production, and also the structure of fillers and existence in their composition of harmful impurity by petrography methods at the stage of prospecting works in the pits that has to raise transport and operational indicators of asphalt concrete and their durability. |
