Abstract
The utilization of elevated temperatures to accelerate the thermal oxidation of HDPE geomembranes was found to be relevant and appropriate. Elevated incubation temperatures up to 85° C did not cause changes in microstructure that could lead to fluctuation in tensile properties. Thus, the temperature acceleration methodology can be applied to investigate the thermal degradation of other isotropic polymeric materials. The importance of antioxidants on the longevity of polyolefin geosynthetics is hereby demonstrated by this study using an HDPE geomembrane. For engineering systems that require long service life, appropriate formulated polyolefin product must be required. The OIT test is a simple method to assess the importance of the antioxidants. Furthermore, OIT can be included in a specification. However, for comparing different types of antioxidants, OIT test must be used together with oven aging to evaluate the depletion rate.
