Bitumen, the air blown of heaviest petroleum cut, is widely using in road industry. This is to its good adhesivity, waterproofing and low cost. Some defects such as high temperature flowing (end in rutting at high temperatures) and low temperature cracking (end in brittle behavior in winter) have should to using some modifiers. In this work PCC and GTR first separately and then in combination together have been used to bitumen modification. Dynamic Shear Rheometery (DSR) in both frequency and temperature sweep modes were utilized to evaluate rheological modification. Results showed that using both modifier in optimum content, 10% of each them, leads in increasing both rutting temperature and also modification of low temperature flexibility of binder<\div>
