EXPERIMENTAL ANALYSIS OF GEOTEXTILE SEPARATOR IN THE GEOSYNTHETIC COMPOSITE

초록

By the reason of geotechnical structures, the demand of geocomposite, especially drainage geocomposite, has increased continuously. Since thermal bonded nonwoven geotextile plays an important role as a separator in geocomposite, expemental analysis has been carried out to evaluate the various properties of geotextile. In this research, a thermal bonding type geotextile was used. The thermal bonding type geotextile takes on a compressed form, and its thickness is thinner than the needle punching geotextile with the same weight; thus, the thermal bonding type geotextile effectively performs the separation effect, and also has excellent tensile feature. With all these, the thermal bonding type geotextile is widely used as a geosynthetic.
