- An apparatus was developed to measure the in-plane hydraulic conductivity of geotextiles. The apparatus is capable of measuring geotextile transmissivities under specified constant hydraulic heads, subject to simulated stress conditions, and in the confinement of soil. Using the new apparatus, a nonwoven geotextile and a woven-nonwoven composite geotextile were tested to measure their in-plane hydraulic conductivities under various normal stresses. Excellent repeatability of the test results were obtained. Three means of confinement for the geotextile (namely, using rigid blocks, flexible membranes, and soil) were employed for simulation of the in-soil condition. In addition, geotextile specimens retrieved from a field embankment were tested to examine the changes in its transmissivities from those of fresh specimens.
