Descripción
This doctoral dissertation aims to present the main results of the half-warm mix recycled asphalt (HWMRA) mixtures with total recycled asphalt pavement (RAP) contents equal to 100% using a continuous asphalt mixing plant specially designed for the production of this technology by Sacyr. To achieve this goal, a set of in-plant samples were collected to determine the reproducibility of up-scaling the laboratory mix design to an asphalt plant. Moreover, a sampling campaign was conducted to determine if the wearing course asphalt mixtures meet the minimum percentage of 98% of the benchmark density after compaction with conventional machinery. his research has demonstrated the viability of using more competitive and sustainable engineering solutions compared to conventional hot mix asphalt mixture, such as half-warm mix recycled asphalt mixtures (HWMRA) mixes with a total recycled asphalt (RAP) content for their use in the binder and wearing course asphalt mixtures of road pavements. This technology allows the possibility of recycling mixtures with high and total RAP contents, obtaining results in terms of mechanical properties very similar to hot mixes, which makes it possible to reduce the GHG emissions, manufacturing and compaction temperatures and consumption of materials while improving the safety of the workers.
