Modified bituminous materials can bring real benefits to highway maintenance/construction, in terms of better and longer lasting roads, and savings in total road life castings. This paper present the effect of there novel modifier as Precipitated Calcium Carbonate (PCC) and two type of nanoclay on rheological properties of bitumen binder. Various blends of modifier and bitumen were selected and empirical rheological test were conducted on short term and long term aging condition. Nanocomposite morphology of bitumen and nanoclay was also investigated by using XRD technique to achieve the best structure. The result show that depends of type, properties and content of modifier, aging resistance improve
