  7. Abstract:
  8. The objective of this research is evaluating the effect of filler type and content on the characteristics of asphaltic materials. The properties of the asphalt mixture are greatly influenced by its components. As asphalt mixtures are composed of two prominent components, aggregates and binder, the change in type and contents of these materials may lead to altering the performance of asphalt mixtures. Aggregates in the asphalt mixtures are categorized into three groups based on their particle sizes: coarse aggregate, fine aggregate and mineral filler. The effect of filler on the characteristics of asphalt mixtures can be examined by changing the type and content of filler and holding the other parameters as constant. In this study, the effect of two traditional filler (Silica sandstone powder and Portland cement) and a new waste lime powder (Eggshell) on the performance of asphaltic materials are evaluated. For this purpose, the effect of filler on the strength of asphalt mixtures against different pavement distresses such as rutting, fatigue cracking, and stripping will be discussed by using effecient experimental tests. Consequently, this research will present an approach for engineers to proceed on choosing the appropriate type and content of filler based on the conditions and materials of the projects
