Abstract
PVA geotextiles/HDPE geomembrane composites were produced to evaluate their applicability as a water barrier liner for waste landfill. The engineering properties of these geotextile composites, i.e. the tensile and tear properties, AOS (apparent opening size) and hydraulic properties, were examined and compared with those of geotextiles generally used in waste landfill. The UV and chemical resistance tests showed that these geotextile composites exhibited improved applicability as a water barrier liner in waste landfills than the generally used geotextiles. Finally, these geotextile composites have stable long-term performance according to their creep behavior.
