Geosynthetics: Characteristics and Testing

Abstract

Geosynthetics are polymeric materials that are used in below-grade construction in a broad and ever-increasing range of applications. The majority of the applications generally fall into the areas of geotechnical, environmental, transportation and hydraulic engineering. A number of specific applications using geosynthetics will be described in Chapters 13–19, 25–27 and 29, 30. Before dealing with applications, however, it is necessary to present the salient characteristics of the various geosynthetics and the most relevant test methods and properties. This chapter is focused on providing that type of background material. While the literature is abundant with references on geosynthetic properties and test methods, this review is quite brief. It follows the general description in Koerner (1998), which is more detailed.
