Feasible Use of Recycled Concrete Aggregates with Alumina Waste in Road Construction Cabrera, Manuel López Alonso, Mónica Garach Morcillo, Laura Alegre Bayo, Francisco Javier Ordóñez García, Bonifacio Javier Agrela, Francisco Recycled aggregates Recycled alumina waste Civil infrastructures Road section Real scale The management of different industrial by-products, such as recycled aggregates from construction and demolition waste and alumina by-products, as well as the reduction of landfill deposits by incorporating these products in a second life cycle, were the focus of this work. The aim of this study was to demonstrate the technical viability of using these waste and by-product as a material for road pavement base layers. For this purpose, a real-scale application was carried out, and the behavior of three types of materials, applied on a section of an experimental road under real vehicle traffic conditions, was studied and compared. Three materials were used in these sections applied in the road sub-bases. First, a control material composed of a type of artificial gravel was used to be compared with the rest of materials; the second material was composed of recycled aggregates, and the third was composed of a mix of recycled aggregates and alumina waste. The results concluded that the effectiveness of the sections built using recycled aggregates and alumina waste was very positive and similar those constructed using natural aggregates. 2021-05-26T07:57:28Z 2021-05-26T07:57:28Z 2021 info:eu-repo/semantics/article Cabrera, M.; López-Alonso, M.; Garach, L.; Alegre, J.; Ordoñez, J.; Agrela, F.
