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.
