The object of the researches presented in this paper were limestone filler as well as basaltic and melaphyre fillers obtained from de-dusting system of the Asphalt Plant. The purpose of the researches were comparative analysis of structural and functional properties of mineral filler specimens that differ in nature as well as qualitative and quantitative assessment of the fillers structure. The research results show that limestone filler differs significantly in specific surface area, grain size distribution and morphology of the grains from the other two types of fillers. These properties are of significant influence on physical and functional properties of the samples of mastics prepared on the base of various types of mineral filler and D 50 penetration grade bitumen.
