Resumen
The use of materials from the recycling of the asphalt binder of a flexible pavement has become an alternative for the preparation of hot asphalt mixtures (MDC), using a percentage of the dosage with material from the R.A.P. These asphalt mixtures must comply with the same technical characteristics stipulated in INVIAS, for a hot asphalt mixtures (MDC) containing only virgin materials; This requires the use of a material that functions as a rejuvenator of the properties of the materials found in the R.A.P. One way to rejuvenate the properties of R.A.P materials is to include burned motor oil (WEO). In Colombia this method has been little explored, despite the conditions and materials for the preparation of this type of mixtures. The problem arises by not knowing what is the optimal percentage of inclusion of WEO, which allows an asphalt mixture with characteristics similar to what is established in the technical specifications for an MDC-19 mixture. Which contributes to the environment and brings economic benefits. In this project three types of hot asphalt mixtures with different inclusions of WEO, T0 (0% of WEO), T1 (5.5% of WEO), and T5 (7.5% of WEO), and 35% of R.A.P. The granulometric characteristics of the virgin aggregates (gravel 68.40%; sand 31.31% and fine 0.29%) and the aggregates of the RAP (gravel 20.83%; sand 79.17% and fine 0%) were determined ), in order to assess whether they met what was specified for an MDC-19. 18 Marshall type briquettes of diameter 101.1 mm were manufactured, with 6 briquettes for each type of treatment, compacted with 75 strokes per face, on which they were determined: the percentage of air voids, stability, flow, stability-flow ratio, susceptibility to water using the indirect tensile test. According to the data obtained from the stability and flow for each treatment, the respective modules of each mixture were determined with the different treatments, which were modeled in three different types of structures, obtaining as a result, that by including WEO in asphalt mixtures favorable result for the properties of materials from the RAP
