Abstract
In practical construction works, installed geotextiles used as filter-sheets are often kept uncovered for several months to a year. Since the friction between geotextiles and rocks due to wave or wind action is severe, the abrasion resistance is an important factor for selecting geotextiles. In this paper, the results of the abrasion resistance test (JIS D 4604) for eight different geotextiles including three non-woven geotextiles, four woven geotextiles, and a multi-layered woven geotextile are presented. The test results are shown in terms of the percent strength retained. Among the test results, 1) the usual woven geotextiles showed a low percent strength retained (about 40%), 2) the coated woven geotextiles with synthetic resin and the multi-layered woven geotextiles showed a good percent strength retained (more than 90%), 3) the non-woven geotextiles showed a moderate percent strength retained (about 65%). Further, weft strands of the usual woven geotextiles shifted laterally and which did not occur with resin coated geotextiles.
