Due to age-hardening (temperature cycles, wetting-drying, ultra-violet and traffic loading) or due to extreme cold weather conditions, the stiffness of the binder increases, the relaxation capacity decreases, the binder becomes more brittle, the self-healing potential and fracture resistance of the bitumen decreases, and cracking of the interface between aggregates and the binder occurs (Liu et al.
