摘要：One important role in asphalt mixture performances is represented by the filler content and characteristics. This research aims to assess the potential usage of industrial waste powders as replacers of the standard limestone filler in asphalt mixture composition. First of all, an SEM and EDX analysis was carried out to figure whether this industrial waste can be used in asphalt mixture composition by comparing the results of the industrial wastes with the properties of the standard filler. After a chemical evaluation, laboratory investigations were carried out to characterize the materials in terms of geometrical and physical properties. The research study involved sixteen dosages of limestone filler with four different types of industrial waste powders in different percentages used. The results obtained from laboratory testing suggested that the inclusion of industrial wastes in the manufacture of asphaltic mixtures may have benefits for the construction industry, the waste management sector, and also for the environment.
