Abstract
A most frequently asked question regarding all types of geomembranes is, "How long will they last?" This paper answers the question for exposed geomembranes assuming that they were properly designed and installed. Ultraviolet radiation, elevated temperature and full oxygen are available which shortens the service lifetime of a geomembrane. Ultraviolet fluorescent tube weathering devices per ASTM D7238 were used for incubation purposes. Five different geomembranes were evaluated. Each material was incubated at 80, 70, and 60 degrees C until 50% reduction of strength and elongation occurred. The data was then extrapolated down to 20 degrees C for laboratory halflife values and for comparison with the nonexposed condition. Results for geomembranes vary from 47 to 97 years with high density polyethylene (HDPE) being the highest.
