Zusammenfassung:	Scavenging compounds and compositions useful in reducing sulfide emissions from asphalt, such as polymer-treated asphalt, are disclosed. The scavenger compositions may include sulfide-scavenging agents. The scavenger compositions also include a metal-containing compound and optionally a solvent. Any of the compositions, sulfide-scavenging agents and metal-containing compounds may be anhydrous. Methods of using the compositions to reduce hydrogen sulfide emissions from asphalt are also disclosed. L'invention concerne des composés et des compositions de piégeage utiles pour réduire les émissions de sulfure de l'asphalte, tels que l'asphalte traité par un polymère. Les compositions de piégeage peuvent comprendre des agents de piégeage de sulfure. Les compositions de piégeage comprennent également un composé contenant du métal et éventuellement un solvant. L'une quelconque des compositions, des agents de piégeage de sulfure et des composés contenant du métal peut être anhydre. L'invention concerne également des procédés d'utilisation des compositions pour réduire les émissions de sulfure d'hydrogène à partir d'asphalte.
