|Abstract(s):||There is an increasing concern about the recycling and reuse of wastes in differ-ent areas. This research aims to analyze the technical viability of the use of Reclaimed Asphalt Pavement (RAP) and Steel Slags (SS) for the composition of asphalt mixtures for surface lay-ers. Therefore, three asphalt mixtures AC 10 were designed: without recycled materials (R), with 30% of RAP (F) and with 30% of SS (A). They were mechanically and superficially as-sessed. Their water sensitivity and the permanent deformation were similar. The mixture A pre-sented higher stiffness modulus and lower fatigue resistance when compared to the other ones. The best sound absorption and mechanical impedance found were for A and the worst ones were for F. Mixture A had smoother macrotexture if compared to the other mixtures. The as-phalt mixtures had similar friction. It can be concluded that these wastes can be incorporated in asphalt mixtures for surface layers.|
