Relationship of SHRP Rutting Parameter with Asphalt Paving Mixture Rutting abstract

This paper aims to develop the relationship between rutting parameter of asphalt (G﹡/sin δ ) by conducting dynamic shear rheometer (DSR) tests with the rut depth values obtained by using wheel track device. The twenty asphalt mixtures have been prepared with twenty types of unmodified and SBS modified asphalts and one type of aggregate . The twenty base and modified asphalts have been used to prepare asphalt paving mixtures required to conduct wheel track tests. The prediction model of asphalt mixtures rut depth related to asphalt rutting parameter (G﹡/sin δ ) values have been founded . In addition the minimum limits of (G﹡/sin δ ) of aged asphalt have been gotten as 3.25 kPa for Iraqi asphalt cement
