 This study investigated the feasibility of producing hot-mix asphalt, HMA, with recycled concrete aggregate, RCA, as a partial substitute for natural aggregates, NA. The results showed that the mechanical behavior of the HMA progressively deteriorates as the RCA content increases. However, this decrease in mechanical performance is acceptable up to a 15% RCA of coarse NA, whereas for higher dosages this alteration is abrupt. Additionally, the RCA only generates sustainability benefits at a 15% replacement amount.
