The article discusses the properties of crushed stone-lime asphalt concrete and the conditions for obtaining a high-quality road surface during its application. The results of the study of replacing mineral powder in crushed stone-asphalt concrete with dust, dust from cement plants and dust from pyrite slag, as well as a study of the stability of the quality of bitumen in time to normal and high temperatures are described. However, the selected areas of using cement plant dust cannot be considered particularly promising, since in the above methods, cement plant dust is easily replaced by chalk and limestone. In this regard, it is more promising to use dust from cement plants to obtain nitrogen-calcium fertilizers, mainly containing calcium nitrate.
