摘要：
A method for forming a modified asphalt binder composition, the method comprising preparing a phosphorus pentasulfide-binder concentrate by introducing and mixing phosphorus pentasulfide and asphalt binder, where the phosphorus pentasulfide-binder concentrate includes greater than 0.5 parts by weight phosphorus pentasulfide per 100 parts by weight asphalt, preparing a polymer-binder concentrate by introducing and mixing polymer and asphalt binder, where the polymer-binder concentrate includes greater than 5 parts by weight polymer per 100 parts by weight asphalt, and introducing and mixing the phosphorus pentasulfide-binder concentrate with the polymer-binder concentrate to form a modified asphalt binder composition.
