In this work, surface course aging was modeled by Response Surface Methodology (RSM). The Marshall specimens were placed in a conventional oven for time and temperature conditions established on the basis of the environment factors of the region where the surface course is constructed by AC-20 from the Ing. Antonio M. Amor refinery. Volatilized material (VM), load resistance increment (ΔL) and flow resistance increment (ΔF) models were developed by the RSM. Cylindrical specimens with real aging were extracted from the surface course pilot to evaluate the error of the models. The VM model was adequate, in contrast (ΔL) and (ΔF) models were almost adequate with an error of 20 %, that was associated with the other environmental factors, which were not considered at the beginning of the research.
