ABSTRACT
The use of reinforcement geosynthetics to prevent localized collapses over cavities is now relatively common. During the REGIC research project, an innovative geosynthetic solution has been developed. It includes a specific reinforcement geosynthetic coupled with an autonomous and remote warning device to detect, to locate and then monitor a localized collapse or sinkhole. This study identifies technically and environmentally the implementation conditions of this innovative instrumented geosynthetic solution compared to the traditional solution. The Life Cycle Analysis is realized to carry out this comparison from an environmental point of view. The results, including a sensitivity analysis aim to provide information on the environmental performance of the developed instrumented solution in a R&D framework. This detailed analysis is extended to most current other possible solutions with same level of performance and safety. This life cycle analysis finally resulted in the publication of an EPD® for the geosynthetic range concerned.
