Abstract: A modified asphalt binder with improved elastic properties and methods of making such modified asphalt binder. The modified asphalt binders may include one or more of an asphalt binder, a solvent deasphalted (SDA) pitch, a polymeric material, and optionally, a ground tire rubber. The disclosed modified asphalt binders exhibit properties consistent with decreased susceptibility to rutting and thus may be used in asphalt concrete applications.
