- Abstract
- This study focuses on evaluating the engineering properties of three types of geogrids (warp knitted, woven, and membrane drawn geogrid). Short-term tensile properties of the membrane drawn geogrid showed very low elongation results compared to the other types. However, estimated long-term creep deformation indicated that the 30 % of Tult loading level was the optimum value that satisfied the creep criteria in the case of membrane drawn geogrid (60 % in warp knitted geogrid and 65 % woven geogrid). The durability test results showed that the membrane drawn geogrid had good resistance to installation damage, chemical, biological and ultraviolet compared with the textile type geogrids. The total reduction factors that considered creep, installation damage and durability of the warp knitted, woven, and membrane drawn geogrid were estimated as 2.0, 1.9, and 3.6, respectively.
