The present invention relates to the coagglomeration of random vinyl substituted aromatic/C -C conjugated diolefin polymers With sulfur. Said coagglomerate is storage stable and easily blended with asphalt under a variety of mixing conditions. Further, polymer/asphalt blends prepared with the sulfur coagglomerated polymers show improved storage stability against phase separation.
