In Europe, RAP recycling can be realized by adding a soft enough virgin binder, the penetration grade of which is normally determined by the log penetration rule [20], and in many cases, at not very high RAP contents, real rejuvenator is not necessary.
The rejuvenator was added to the aged asphalt samples at different contents by weight according to the respective ageing duration and cycle number (e.g., for group 1 asphalt sample, though the second and the third cycle ageing durations are the same 40 min, rejuvenator contents for these two cycles recycling may be different).
In terms of rejuvenator, its diffusion behavior in the asphalt binders at different aging states can be studied to guide the use of regenerative agents.

The rejuvenator percentage affected greatly the performance-based properties of the blend of aged binder and the rejuvenator (Shen et al.
The grade and optimal amount of a suitable rejuvenator depend on the composition and properties of RAP, especially on the properties of the aged bitumen, which may be identified in experimental investigations conducted in a laboratory.
As the increment of RAP in the mixes resulted in an increase in the stiffness, a decreasing trend in the flow value was observed due to the increased RAP content for both rejuvenators. In addition to these tests, the loss of stability was measured and found to be satisfactory for all the mixes, with the exception of CM with 50% of RAP, although the difference was insignificant.

Two types of nonmodified RAP, two virgin binders, and two rejuvenators were used.
VB1 aged faster than VB2, and its aging was more influenced by rejuvenators.
