Reexamination of Traditional Testing Techniques for Determining WRCs of Woven Geotextiles in Full Suction Range
Woven Geotextiles Have Been Widely Used in Soil Infrastructures for the Reinforcement Purpose. the Hydraulic Properties of a Woven Geotextile Are Not Major Reinforcement Design Parameters and the Water Retention Capability of a Woven Geotextile is Often Ignored. the Traditional Testing Techniques Were Designed for Soils or Nonwoven Geotextiles, But Not for Woven Geotextiles. Nowadays, a New Type of Woven Geotextile with Wicking Fibers Was Developed Which Could Be Used for Both Drainage and Reinforcement Purposes. However, There Are No Proper Testing Techniques to Determine the Full-Range Water Retention Curve (WRC) for a Woven Geotextile, Let Alone for the Wicking Geotextile. This Paper Aimed at Proposing a Proper Testing Technique to Determining the Full-Range WRC for the Wicking Geotextile and to Compare the Water Retention Capability of Wicking and Non-Wicking Geotextiles. Firstly, the Traditional Testing Techniques Were Re-Examined to Check the Suitability for Characterizing the WRCs of Woven Geotextiles Whose Pore Size Distributions Were Anisotropic. Secondly, a Proper Testing Technique Was Proposed and the WRCs of Different Types of Woven Geotextiles Were Determined. Thirdly, the WRCs of Wicking and Non-Wicking Geotextiles Were Compared to Demonstrate the Advantages of the Wicking Geotextile to Hold and Transport Water under Unsaturated Conditions. Finally, the Effect of Wicking Fiber on the Water Retention Capability of the Wicking Geotextile Was Quantified.
