Abstract:The research results described in this TechBrief are from four volumes on the subject of durability of geosynthetics for highway applications. Various aspects of geosynthetic durability were addressed in order to develop procedures that could be used to predict long-term strength losses of geosynthetics used in highway applications. The study was conducted in stages, each stage building on the knowledge previously gained. The main objectives addressed were to: (1) develop testing protocols necessary to quantify any strength reduction due to aging or stress (stress cracking only) mechanisms for polymeric reinforcement materials (geosynthetics), and (2) develop testing protocols for confined stress-strain testing, which could more accurately characterize key engineering properties.
