Abstract (EN): Over the last few years, the environmental sustainability has been demanding a progressive increase in the waste recycling in the construction industry. As regards to the use of construction and demolition (C&D) recycled materials in geotechnical works, the valorization is performed mainly in road construction. However, the fine-grained fraction of C&D recycled materials is commonly not considered appropriate for base and sub-base layers of transport infrastructures, being frequently landfilled instead of reused. This paper assesses the feasibility of using fine-grained C&D recycled materials reinforced with geogrids, particularly for their use in unpaved rural roads. The physical, mechanical and environmental characterization of a fine-grained C&D recycled material, as well as its direct shear behaviour is presented and discussed. The characterization of the interfaces between this recycled material and two geogrids is also evaluated through large-scale direct shear. The study focuses mainly on the influence of the moisture content of the recycled C&D material and geogrid type. The results provide evidences of the proper geotechnical and geoenvironmental behaviour of recycled materials and the feasibility of their reinforcement with geogrids. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
