Abstract
This chapter describes the various long-term geotextile degradation mechanisms which lead to the eventual limit of the material's service lifetime. It also presents procedures and results for the lifetime prediction of four different geotextile types insofar as UV degradation in laboratory weathering devices is concerned. Using incubation at elevated temperatures of 80, 70, and 60°C, the procedure results in half-lives in laboratory simulations which are then extrapolated to an arbitrary temperature of 20°C. Furthermore, using the UV radiation in Phoenix, Arizona, it converts the previously obtained half-life responses to that specific field location at the same 20°C temperature. These lifetime predictions in the laboratory and in Phoenix are presented and compared with each other. The lifetime at any worldwide location can be determined in a similar manner.
