Development of Protocols for Confined Extension/Creep Testing of Geosyntheticsfor Highway Applications

摘要

This report presents the development and verification of a testing protocol andprotocol equipment for confined extension testing and confined creep testing for geosynthetic reinforcement materials. The developed data indicate that confined response significantly improves stress strain response of geosynthetic materials, especially nonwoven geotextiles. Current use of unconfined stress-strain response appears overly conservative.
