Description:
The effects of freeze-thaw cycling on the tensile strength of 19 geomembranes and 31 different seam types were investigated. The study was performed in three parts using different test conditions. Part I involved incubating unconfined specimens in freeze-thaw cycles and then performing tests at room temperature. Part II involved incubating unconfined specimens in freeze-thaw cycles and then performing tests at a temperature of -20°C. In Part III, the test specimens were confined at an elongation corresponding to 25% yield or break strength during the freeze-thaw cycles and then were tested at room tempera ture. The paper describes the results of each part of the study separately and then investigates comparisons of Parts I versus II and Parts I versus III. As of 50 freeze-thaw cycles, the tentative conclusion is that neither geomembrane sheets nor their associated seams are adversely affected by the different conditions imposed. This tentative conclusion will be further challenged after completion of the 100 and 200 cycle testing.
