摘要：
A modified asphalt binder composition prepared by combining asphalt binder, phosphorus pentasulfide, and less than 2.5 parts by weight unsaturated polymer, per 100 parts by weight asphalt binder, to thereby produce a modified asphalt binder composition characterized by an elongation recovery at 25° C., as determined according to AASHTO T301, of greater than 75%, where the phosphorus pentasulfide includes a blend of P4S10 and P4S9.
