MORALES FOURNIER, JESSIKA et al. Influence of the Addition of Reclaimed Asphalt Pavement (RAP) on the Performance of Hot Mix Asphalt Mixes. Ing. Desarro. [online]. 2025, vol.43, n.2, pp.155-176.  Epub 01-Jul-2025. ISSN 0122-3461.  https://doi.org/10.14482/inde.43.02.451.789.

The use of recycled asphalt pavements serves as an alternative to reduce the reliance on non-renewable resources. The deteriorated pavement can be recycled as a feasible solution. It is therefore important to study the influence of this material on the behavior of the mixes. In this research, asphalt mixes with 10% and 20% RAP, in the 0-l0mm fraction, using two bitumen contents (4.0% and 4.5%) are studied. The mixes with RAP are compared with a conventional asphalt mix. Parameters such as Marshall stability and flow, water sensitivity, permanent deformation, and stiffness modulus were analyzed. The general results show that the behavior of the recycled mixes is similar to or better than the conventional mix. The best results were obtained for the addition of 20% RAP.

Palabras clave : reclaimed asphalt pavement (RAP); rutting resistance; stability; stiffness modulus.
