Asphalt concretes are made of asphalt binders and aggregates. Although asphalt cement is predominantly considered the binder holding the aggregates together, the actual product used to com1ect larger-size aggregate particles is the asphalt mineral filler mastics. It improves the resistance to permanent deformation in asphalt concrete mixtures by improvement of rheological properties of asphalt binders through a filler effect, and by acting as a microcrack arrester as well as improving the bonding interaction between asphalt binder and aggregates. Samples having different types of filler were prepared and optimum binder content was determined by Marshall Test procedure. Optimum filler content was determined considering the filler/bitumen ratio and filler ratio. Creep test, was carried out to determine the mixture properties and performance. Utilization of waste material as filler material shall reduce cost and contributes to the conservation of the environment without compromising the performance of the asphaltic concrete.
