Controllable aging, cracking, healing
This study validates the mass-composite activation energy hypothesis, demonstrating that aging, cracking, and healing kinetics of recycled binder blends can be predicted linearly from component activation energies.

Aging activation energy (Eacr) of recycled binder blends is lower than that of RAP binders
With increasing RAP binder content, blends show decreased cracking activation energy (Eac) and increased healing activation energy (EaH)
Measured activation energies of blends agree with calculated mass-composite activation energies
