Development of an accelerated creep testing procedure for geosynthetics.

The extrapolation procedures to predict creep strains from elevated temperature tests do not apply to all types of polymers used in the geosynthetics industry. The investigation of the applicability of temperature-controlled accelerated creep tests in predicting creep strains to longer time intervals offered a practical and economical solution for testing various geosynthetics in reasonable time frames. The proposed research aimed to accelerated creep tests. The report can help the geotechnical engineers in evaluating creep strains at longer time frames from accelerated tests for many geosynthetics used in soil reinforcement applications
