Description

In this paper, based on the results of tensile tests conducted on collected samples and samples after accelerated exposure testing, a durability assessment equation using an exponential function model for the degradation prediction of geomembranes is constructed and proposed. In 2009 and 2018, a total of 127 samples were collected from landfill sites where geomembranes had been installed for over 20 years. Additionally, for long-term degradation prediction, a portion of the collected samples was subjected to accelerated exposure testing using a metal halide lamp weathering test apparatus. The proposed evaluation equation reports statistically significant results indicating the accurate assessment of the tensile property retention ratio of geomembranes.
