Performance of Asphalt Mixtures with High Recycled ...

To improve the cracking resistance of asphalt mixtures with high recycled asphalt pavement (RAP) and reclaimed asphalt shingles (RAS) contents, one approach is to use a recycling agent (RA) (i.e., rejuvenator) to potentially restore the performance properties of the aged binder.
