The objective of this paper is to analyse the effects of aging on geomembrane durability and to design an accelerated test (a few months duration). This test takes into account the different aging parameters without changing the aging mechanisms observed on site. Different analysis and mechanical tests are considered to characterize the geomembrane changes. Results show good agreement with observations on site.
