Abstract
The paper presents the results of laboratory analysis of permeability coeffcient tests carried out in the modied soil-geotextile permameter, recommended in ASTM standard D 5101-90. Laboratory tests were performed on nonwoven geotextile K-500 and clayey sand. The analysis of tests results indicates that in the design calculations for nonwoven geotextile used as flters not only permeability coeffcient of geotextile and soil, but also permeability coeffcient of soil-geotextile system should be determined. The change of the fnal permeability coeffcient of soil-geotextile system based on the initial values of the permeability of geotextile and soil as well as hydraulic gradient were proposed.
