Blends of vacuum bottom residue with wastes of polyethylene and styrene-butadiene rubber were prepared and their morphology and rheological properties were studied. Since the applied stresses on bitumen in asphaltic pavements are dynamic, the dynamic mechanical behavior of bitumen is of a prime importance. Thus the ratio of G*/sinδ at 10 rad/s was used to estimate the resistance of bitumen to rutting. It was found that the values of this ratio and other rheological functions such as loss, storage and complex module are in such a magnitude that cracking at low temperatures and rutting at high temperatures are avoided. The morphological studies showed that the wastes particles had homogeneous dispersion in vacuum residue. Concerning these rheological properties of bitumen it is concluded that a proper application is found for recycling the cosidered wastes.
