Geotextile are utltized for prevention of soil draw out and filtration material. However testing methods and quality standards have not been established yet in Japen. So, we proposed new test methods for geotextile filtration applicability.
Those methods of testing are; A. O. S (apperent opening size) test, permittivity test and accelerated clogging test.
The test results show that proposed new test methods are effective to estimate geotextile filtration performance. But tepe of A. O. S test method must be carefully selectted according to types of geotextile.
