The safety and environmental impact of an asphalt recycling agent should be considered when selecting a rejuvenator or recycling agent. An effective rejuvenator will not only meet performance specifications but also consider worker safety and exposure issues and help reduce carbon emissions. These considerations include whether the material contains volatile organic compounds, or VOCs, has any harmful odors, or requires personal protection equipment for handling. Storage and transport should also be reviewed including flashpoints, ambient temperature conditions, storage conditions, and any special equipment required for pumping.
Understanding these attributes can help plant managers incorporate an asphalt rejuvenator into their operations. Different products have different requirements, and evaluating the most efficient and available approach can help save both time and costs. Rejuvenators can be introduced to a mix at several points in the process including adding it to the RAP belt feeding the drum, injecting it into virgin binder feed stream, or bulk blending with the virgin binder.
