Abstract (EN): The installation process may cause unwanted changes in the mechanical behaviour of the geosynthetics. In this work, some geosynthetics used in the base liner system of landfills (a combination of a geotextile, a geomembrane and a geosynthetic clay liner) were submitted to mechanical damage under repeated loading tests (procedure adapted from EN ISO 10722), being monitored the changes occurred in their short-term behaviour. The mechanical damage under repeated loading tests consisted in placing the geosynthetics between a flexible base (granite residual soil with a relative density of 80%) and an aggregate and submitting them to cyclic dynamic loading. The geosynthetics were damaged with a natural aggregate (gravel 14/20), a recycled ceramic aggregate and corundum (synthetic aggregate used in EN ISO 10722). The damage suffered by the geosynthetics was evaluated by monitoring changes in their tensile, tearing (only for the geomembrane) and static puncture properties. © Springer Nature Singapore Pte Ltd. 2019.
