The object of the studies presented in this paper were the samples of mineral fillers obtained from a dust extractor of asphalt plant as well as mastics containing these fillers. The work consists of two parts. In the first part a comparative analysis of the structural and functional properties of the limestone, basaltic and melaphyrc fillers was carried out. To this end, the grain-size distribution, specific surface area, Rigden voids as well as bulk volume concentration and activity index of fillers were determined. In the second part, quantitative and qualitative estimations of the stiffening properties of these fillers in mastics were performed. A search for the quantitative relationship between the filler's structural features and the selected rheological properties of mastics was conducted in order to assess a practicability of dusts obtained from a dust extractor of asphalt plant to use in asphalt pavement layers.
