4.1 Designers/specifiers of geosynthetics should evaluate geosynthetic durability as an integral part of the geosynthetic specification/selection process. This guide is intended to guide a designer/specifier through a systematic determination of degradation concerns based on the intended geosynthetic function or performance characteristic. This guide then provides a guide to select available test methods for experimentally evaluating geosynthetic durability and to identify areas where no suitable test exists. 4.2 This guide does not address the evaluation of degradation resulting from manufacturing, handling, transporting or installing the geosynthetic. | ||||||||||||||||||||||||||||||||||
| 1. Scope | ||||||||||||||||||||||||||||||||||
1.1 This guide covers a designer/specifier through a systematic determination of those factors of the appropriate application environment that may affect the post-construction service life of a geosynthetic. Subsequently, test methods are recommended to facilitate an experimental evaluation of the durability of geosynthetics in a specified environment so that the durability can be considered in the design process. (A) Functions are used in the context of this guide as terms that can be quantitatively described by standard tests or design techniques, or both. (B) Other performance characteristics are qualitative descriptions that are not yet supported by standard tests or generally accepted design techniques. Note—during the placement of fresh concrete in a geotextile flexible form, the geosynthetic functions temporarily as a filter to allow excess water to escape. 1.2 This guide is not intended to address durability issues associated with the manufacturing, handling, transportation, or installation environments. | ||||||||||||||||||||||||||||||||||
