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 Nanoclay on engineering properties of asphalt concrete. Various empirical and fundamental tests such as Marshall test, indirect tensile strength, resilient modulus, dynamic creep and diametric fatigue have been investigated in this research. These tests have been conducted at different temperature and various lording forms. The results show that nanoclay modifier can improve cohesive and strength of the mix by increase in marshal stability, indirect tensile, resilient modulus but has non proper response in fatigue behaviour. Precipitated Calcium Carbonate can improve fatigue response of the mix but has not salient effect on marshal stability and indirect strength.
