The installation damage of woven rib geogrids under various backfills
Four different strengths of PVC-coated PET flexible geogrids from a single manufacture were placed in five different typical soils for the purpose of evaluating the amount and degree of installation damage. A series of single rib strength tests (GRI-GG1) and in-isolation junction strength tests (GRI-GG2) were performed. Based upon the test results, the tensile strength retained for flexible geogrid placed within fine grained soil, sandy soil, gravel with some fine soil, and crushed stone gravel are 83 % to 99 %, 85 % to 96 %, 66 % to 95 % and 57 % to 88 %, respectively. The reduction factor for tensile strength due to installation damage is significantly related to soil type and varies from 1.05 to 1.70. The retained strength of junction for flexible geogrid is ranging from 71 % to 100 % for various type soils. The reduction factor for junction strength due to installation damage varies from 1.00 to 1.40 for different type of soils.
