Abstract (EN): The lifetime of the geosynthetics can be shortened by an extended exposition to weathering. So, it is important to evaluate the resistance of these materials against weathering. In this paper, three high density polyethylene geonets (with different chemical compositions) were exposed to weathering, both under natural and accelerated conditions. The natural weathering tests were carried out in Portugal (24 months of maximum exposure), while the artificial weathering tests were performed in a laboratory weatherometer (4000 hours of maximum exposure). The results obtained for the geonets weathered outdoors were compared with the results obtained for the geonets weathered in laboratory.
