- Abstract
The apparent opening size (O95) of geotextile is a physical parameter closely related to the permeability property and/or amount of clogging of geotextile. In this study, since the apparent opening size is an important parameter, the apparent opening size test of geotextile on the wet method was performed and verified the adequacy of that test method. The apparent opening size of geotextile obtained from that test is discussed. Based on a series of constant head permeability test results on the various geomaterials carried out in the past, the effect of the apparent opening size on the permeability of the geotextile is also discussed.
