Abstract:This report presents the development and verification of a testing protocol and protocol 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. This report is part of a comprehensive study on the "Durability of Geosynthetic Materials for Highway Applications."
