Evaluation of Alternative Fillers Usable for Asphalt Mixtures
In this research study, selected fillers originating as stone dust or as back fillers have been used as potential substitutes to normally used limestone filler. They have been analyzed by XRF spectroscopy, density or quality of fine particles. These parameters might influence the effect of used fillers on asphalt mortar properties and mix performance. Two types of aggregates have been selected and alternative fillers have been added to asphalt mix of AC8 type according to modified procedure described by the standard EN 1744-4. For each asphalt mix containing alternative filler stiffness, Marshall stability and resistance to water immersion were determined to indicate the potentials of such substitution to asphalt mix durability and resistance to permanent deformation. From the results it is obvious that the chemical composition might have influence on the asphalt mix stiffness and the resistance to water immersion, similarly the physical properties of fillers will influence the asphalt mortar quality which is crucial for asphalt mix resistance to permanent deformation and moisture susceptibility.
