Despite the advances observed over the last decade, Brazil still suffers from the scarce use of recycled construction and demolition waste (RCDW). On the other hand, most of the roads in the country are unpaved and present low loading support. In this context, the construction of geosynthetic reinforced unpaved roads with RCDW could stimulate the market of recycled materials and increase the performance of these roads. This study aims to evaluate the mechanical damage of two types of geogrids due to in-field cyclic loading of RCDW. The simulation of three scenarios of damage revealed specific reduction factors for each geogrid, which could be easily used in project design. This study reinforces the importance of carrying out investigation of geogrid damage using the specific conditions (material, construction method and loading) of each work. Based on these findings, sustainable development can be implemented using RCDW and provide roads to the society with better operational performance.
