D35 on Geotextile Bags

ASTM International Committee D35 on Geosynthetics has announced a new standard: D7701, “Standard Test Method for Determining the Flow Rate of Water and Suspended Solids from a Geotextile Bag.” In the “Significance and Use” section on D35’s page, the committee notes, “This test method may be used as an aid to design geotextile container systems that contain fine-grained, high water content slurries such as dredged materials to meet special environmental or operational requirements. This test is often used to demonstrate the efficacy of geotextile dewatering to regulatory agencies in determining the amount of dredged material sediment passing through a geotextile and the flow rate for specific high water content materials.”
