abstract = {This research aims to study the recovery capability of
bituminous materials at various levels of damage, taking into account the influence of
several variables such as time, temperature, external forces, and rest periods. Thus, to
explore the recovery due to healing phenomenon, different types of asphalt mixtures were tested under various conditions until their macro-failure by employing the
University of Granada Fatigue Asphalt Cracking Test (UGR-FACT), after which various
conditions were applied in order to induce their recovery (applying heating and
external forces) under different treatment durations. In addition, to explore the role of
recovery capability due to reversible phenomena, the asphalt material was tested
using UGR-FACT by introducing different types of rest periods.
The results indicated that among the variables that could affect the recovery capability
of the material at the macro-crack level, the duration of the healing treatment has little
impact, while the type and amount of binder could have more influence than
temperature. Additionally, the presence of external forces during the healing treatment
could increase the rate of recovery, but it is not sufficiently effective to recover the
initial properties of the material. Thus, regardless of the type of treatment, the amount
of fatigue life recovered in macro-damaged asphalt mixtures is low, prompting the
suggestion that although applying these healing techniques can close the macro-crack,
completely effective healing appears to be more difficult to achieve.},
