Effect of geotextile Static Puncture Strength value on the geotextile-geomembrane interface characteristics
Effect of geotextile Static Puncture Strength value on the geotextile-geomembrane interface characteristics
Over the past decades, the use of geosynthetics has gained popularity due to their ability to improve containment, stability, efficiency, and environmental performance of engineered facilities. However, their utilization has led to the development of interfaces which create potential failure planes within multiple geosynthetic systems. It is therefore imperative to understand the geosynthetics shear characteristics at these interfaces. This study aimed at investigating the influence of the geotextile (GTX) unit mass and geomembrane (GMB) surface texture on the shear characteristics of the geomembrane-geotextile interface. Several laboratory tests were conducted on different geotextiles with varying unit mass values and geomembranes with different asperity heights using the direct shear test apparatus at different applied pressures ranging from 50kPa up to 800kPa. The test results are discussed in detail in this paper.
