Proceedings of the 4,hAsian Regional Conference on GeosyntheticsJune 17-2(), 2008 Shanghai, ChinaENVIRONMENTAL STRESS CRACK RESISTANCE OF GEOMEMBRANEBY NCTL TESTH.Y. Jeon1. Y.S. Jang2and K.Y. Lee'ABSTRACT:The effects of acidic and alkaline solutions from wastes leachate on the machine properties of a 2.5 mm thick highdensity polyethylene (HDPE) geoinembranes (GMs) were examined. Smooth/texiured HDPEGMspecimens were cut into machinedirection (MD) and cross machine direction (CMD) which were immersed in the tanks of notched constant tensile load (NCTL) testapparatus containing acidic waler (pH=4), alkaline water (pH=8) and incubated al 40 and 60°C respectively. The decline in stress crackresistance of HPDE GMs is evaluated using NCTL tester. In acidic and alkaline conditions. HDPE GMs performed the same stresscrack resistance. The increase in temperature and the level of loading shows the decrease in stress crack resistance.
