摘要：

Enhancing the quality, improving the compositions and technology of crushed stone-mastic asphalt concrete are among the urgent problems in Ukraine. The feasibility to use modifying additives in the compositions of asphalt concrete mixtures to improve the quality of crushed stone-mastic asphalt has been defined. For the first time in Ukraine, laboratory studies were carried out on the use of fiber from fly ash from thermal power plants to reinforce hot asphalt concrete mixtures for the construction of road and airfield pavements. The features of the surface topography of the fiber under consideration, the properties of the asphalt binder are investigated, and its bitumen-holding capacity is assessed. The rheological properties of the material are determined. The influence of various powder stabilizers on the structure formation of crushed stone-mastic asphalt concrete mixtures and the properties of crushed stone-mastic asphalt concrete has been established, and fiber from fly ash from thermal power plants has been substantiated to be the most effective reinforcing additive, the most effective modifier, and has shown advantages over traditional additives.
