摘要：	Geosynthetics have evolved from specialty materials considered state of the art in unique geotechnical designs to commonly used construction materials considered state of the practice in many transportation engineering applications. This relatively quick acceptance of geosynthetics can best be explained by their proven track record. Geosynthetics have generally performed as expected, though relatively few installations have yet reached their designed service lives. The term "durability" refers to the ability of geosynthetics to maintain satisfactory performance over time. Durability can be thought of as relating to changes over time of both the polymer microstructure and the geosynthetic macrostructure. The former involves molecular polymer changes and the latter assesses geosynthetic bulk property changes. Definitions of associated terminology, the identification of potential degradation processes, and the systematic selection of standard tests to evaluate both micro- and macrostructure components of durability as they relate to the use of geosynthetics in various transportation engineering applications are examined.
