In this present study, the effect of compaction temperature on the mechanical behavior of base material containing 100% RAP (Reclaimed Asphalt Pavement) with and without asphalt emulsion is analyzed by means of repeated triaxial tests, of the multistage type,to evaluate permanent deformation. The results demonstrated that RAP mixtures exhibit significant susceptibility to permanent deformation at all analyzed stages, and the addition of binder did not provide stabilization to the mixture; instead, it increased their susceptibility to deformation. Conversely, the temperature increases within the compaction range reduced the plastic deformations of RAP mixtures, making them more stable with behavior similar to, and even better than, the analyzed virgin crushed rock aggregate at lower stresses. Therefore, thermal compaction emerges as a viable alternative to mitigate the susceptibility to permanent deformation in the base layer composed of 100% RAP.
