Consistency and Fairness in Geotextile Specifications

by C. Joel Sprague, Nicolon Corp, Norcross, United States,
Marshall Gaddy, Nicolon Corp, Norcross, United States,



Document Type: Proceeding Paper

Part of: Materials: Performance and Prevention of Deficiencies and Failures

Abstract:

By clearly defining required material properties in terms of 'Minimum Average Roll Values' for routine quality control tests and 'Average Test Values in the Weakest Principal Direction' for non-routine tests, the specifier will accurately communicate design-based requirements to geotextile suppliers. This applies to both generic and 'or equal' specifications. Certification from the geotextile's supplier and corresponding detailed test data for the production lot from which the geotextile rolls received on site were taken, should be required for routine Q.C. test properties. Results from independent laboratory testing should be required for non-routine Q.C. test properties. This will provide the necessary documentation that the specifications are satisfied with the desired confidence level. If insufficient test data is available, field conformance testing in accordance with ASTM D4759 should be performed. Field sampling and testing is also very desirable and is especially important on large jobs or jobs involving critical applications of geotextiles.
