Assessment of Engineering Properties of Geosynthetics with Seaming Methods
8 Geotextiles (; 4 woven and 4 nonwoven types), 4 geogrids and 2 geocomposites of [nonwoven/fibers/nonwoven] structure were used as raw materials and the different seaming methods were applied to compare the seam properties of 3 geosynthetics and transmissivity of geocomposites. Tensile strength retentions of these geosynthetics were evaluated as the degree of damage by chemical degradation. Woven geotextiles showed the higher seam strength in the order (SSd-1 < SSd-2) > (SSa-1 < SSa-2) > geospacer without regard to the design strength. For nonwoven geotextiles, the order of seam strength is geospacer > (SSa-1 < SSa-2). Geogrids showed the higher seam strength in the order of band > geospacers but reduction factors were increased in the order of band > geospacer without regard to the geogrid’s compositions. Finally, geocomposites showed the higher seam strength in the order of geospacer > (SSa-1 < SSa-2) but showed the transmissivity in the order of geospacer > (SSa-1 > SSa-2) without regard to the kinds of filled fibers and weight of geocomposite.
