In this experiment, at first, waste polyvinyl chloride was used as an additive in an attempt to improve the performance of bitumen and hot mix asphalt (HMA) in order to minimize the amount of rutting. To further these aims, conventional and rheological tests were conducted on bitumen and all HMA specimens were tested by Marshall stability, flow, and repeated load axial tests. After investigating rutting resistance of HMA samples, the results demonstrated that this waste material could improve the rheological properties of bitumen, and the HMA samples, manufactured by this particular type of bitumen, are more resistant to rutting.
