ASTM D7737 - 11 standard test method for individual geogrid junction strength
This index test method is to be used to determine the strength of an individual junction in a geogrid product. The test is performed in isolation, while in service the junction is typically confined. Thus the results from this test method are not anticipated to be related to design performance. The value of junction strength can be used for ...

ASTM D7701 - 11 standard test method for determining the flow rate of water and suspended solids from a geotextile bag
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 ...

ASTM D7703 - 11 standard practice for electrical leak location on exposed geomembranes using the water lance system
Geomembranes are used as barriers to prevent liquids from leaking from landfills, ponds, and other containments. For this purpose, it is desirable that the geomembrane have as little leakage as practical. The liquids may contain contaminants that if released can cause damage to the environment. Leaking liquids can erode the subgrade, causing further damage. ...

ASTM D7747 - 11 standard test method for determining integrity of seams produced using thermo-fusion methods for reinforced geomembranes by the strip tensile method
The use of reinforced geomembranes as barrier materials has created a need for a standard test method to evaluate the quality of seams produced by thermo-fusion methods. This test method is used for quality control purposes and is intended to provide quality control and quality assurance personnel with data to evaluate seam quality. This standard arose from the need for a destructive test method ...
