The purpose of this research is to evaluate the use of reclaimed asphalt pavement (RAP) in dense hot asphalt mixtures (HMA). The objective is to analyze the physical and mechanical behavior of these mixtures, following ASTM D 1559 and AASHTO T 283 standards. For the design of these hot asphalt mixtures, several aspects were considered, such as the grain size of coarse and fine aggregates, as well as the testing of the virgin AC30 asphalt binder. In addition, the granulometry of the RAP obtained by the “milling” process was considered, using a sample of the asphalt layer of the road in Canal Seco of Comayagua, Honduras. Asphalt briquettes were made and dosed using percentages of 10% and 20% of RAP, compared with a control sample. The results obtained showed that the optimum content is 5.60% for the control sample, 5.25% for 20% RAP and 5.45% for 10% RAP. In terms of mechanical properties, stability 3446 Lb. and flow 10.30/100 in. were found for the control sample, 3743 Lb. and 11.50/100 in. for the sample with 20% RAP and 3546 Lb. and 11.55/100 in. for the sample with 10% RAP. In terms of resistance to moisture damage, values of 95.10% were obtained for the control sample, 93.60% for the 20% RAP sample and 94.30% for the 10% RAP sample. In conclusion, the (HMA) with RAP additions performs well in terms of resistance to moisture damage and compliance with the specified volumetrics.
