MECANICAL PROPERTIES, AOS, PERMITTIVITY AND UNTRAVIOLET STABILITY FOR WASTE LANDFILL APPLICATION OF PVA GEOTEXTILE/HDPE GEOMEMBRANE COMPOSITES

초록

Geotextile related products are mainly used for reinforcement of ground and slope plane, reclamation, dam and tunnel construction, reinforcements for costal embankment and soil retaining wall, railway and road construction, and waste landfill construction etc. Among them, geotextiles(GT) are used for the purposes of protection/reinforcement, filtration, drainage, and even separation [1]. In this study, PVA geotextile/HDPE geomembrane composites were made to examine the waste landfill related properties such as tensile, tear and bursting strengths, AOS (apparent opening size), permittivity of PVA geotextiles, and ultraviolet stability
