Lessons learned from the ASIRI+ project on the use of geosynthetics in load transfer platform

Authors: Alain Nancey, and Laurent Briançon

Geosynthetics are used for the reinforcement of the granular layer acting as a load transfer platform in the case of embankments on piles or rigid inclusions. This article highlights the results obtained on the use of geosynthetics during the French national project ASIRI+ (2019 - 2025), an extension of the ASIRI project (2005-2012), aiming to provide recommendations for the design of a soil reinforced by rigid inclusions with practical suggestions for the installation. Full scale experiments, field monitoring, physical models at the centrifuge, as well as numerical models have been used to get a better understanding of the geosynthetic behaviour, confirming the interest of this reinforcement solution.
