Long-Term Aging of Recycled Binders

The objective of work is to go beyond meeting the initial binder softening requirements and look at long-term performance. It is well recognized that softening the binder can take place at the expense of long-term performance. The example of using solvents, such as diesel, that can be destructive to the binder. In this case, the softened binder will initially meet viscosity and penetration requirements, but will not last long. It is recognized that the environmental aging of a recycle mix can be quite difference from that of a virgin mix. More work is needed to evaluate the effect of the rejuvenator on binder aging. This work is necessary to develop performance-related specifications for the mix and the recycled agent.
