A trial installation can be constructed to check if damage to the geotextiles has occurred after placement and compaction of the aggregate. Test samples of geosynthetic are taken to conduct laboratory experiments to ensure that the samples pass strength requirements.</p><p><strong>Accuracy and Precision</strong></p><p>Testing is straightforward and provides an accurate determination of geosynthetic quality.</p><p><strong>Adequacy of Coverage</strong></p><p>Test samples from rolls of geosynthetic are selected randomly.</p><p><strong>Implementation Requirements </strong></p><p>Experience and special equipment is required to conduct strength tests.</p><p><strong>General Comments</strong></p><p>Before installation of geosynthetic, the geosynthetic properties are checked to confirm quality and adherence to specification requirements. Two samples of the geosynthetic are cut from the roll into 4- to 6-inch (100- to 150-mm) squares. One is sent to the design engineer for approval and the other is kept with a copy of the specifications for comparison with future shipments. Prior to compaction, the geosynthetic should be checked for damage by conducting a trial installation or excavating a small section of aggregate.</p></p>
