With the increasing use of geosynthetics in civil engineering applications, the geosynthetic industry has developed new and more sophisticated materials. As improved geosynthetics are being introduced, it is necessary to assess their durability with respect to the environmental conditions that they will be exposed to. This requires the development of accelerated tests permitting the degradation prediction of geosynthetics in actual use. To address this need, a basic autooxidation scheme (BAS) has been adapted so as to develop a kinetic model for evaluating their mechanical degradation. Based on the experimental data, the model provides estimates of strength loss with time caused by thermo-oxidation.
