Tomorrow's tests for geotextiles will be developed around today's design needs and tomorrow's design requirements. In this paper, current testing needs are reviewed and future test requirements are postulated. Current test needs that are reviewed include: standardized tests for basic fabric properties; standardized performance tests for soil-fabric properties; model studies to evaluate the mechanisms which enhance fabric performance; and studies to define the relationship between physical-mechanical properties and soil-fabric behavior. These needs are discussed in relation to providing the framework for future test development. Future advancements in testing technology are reviewed with respect to modification of existing test methods to provide better characterization of geotextiles and to provide answers to current design questions. Potential test requirements for new applications, new design methods, and new products are postulated. Finally, test equipment development that may be required to meet the needs of advancing test technology is reviewed.
