Beschreibung
Zusammenfassung:	A rejuvenating binder, applicable to the recycling of aged asphalt pavements, composed of: a) a carrier medium, b) a chemical rejuvenating agent, and c) a chemical foaming agent and modifier. Chemical rejuvenating agents are compounds of the disulfide type, or that contain thiol groups, which reverse the oxidative process, fundamental cause of the deterioration of the bituminous binders, reducing the concentration of the more polar compounds of the bitumen and/or the molecular weight of the compounds united by sulfur bonds. The preferred mode of application is in the form of chemical bituminous foam, by adding water that reacts with the functionalized prepolymers with terminal isocyanate groups, releasing carbon dioxide, which acts as a chemical foaming agent.
