INFLUENCE OF STRAIN RATE ON GEOSYNTHETIC REINFORCEMENT PROPERTIES

Strength properties of geosynthetics are often obtained by performing ASTM D4595 wide width tensile tests or GRI-GG1 single rib tensile tests. However, the actual rate of loading of the reinforcement in the field during reinforced earth structure construction may be five or six orders of magnitude slower than the standard ASTM D4595 and GRI-GG1 testing rate. In an effort to investigate the strain rate effects on the engineering properties of different geosynthetic materials, the authors performed strength tests on ten different materials under different strain rate conditions. In this paper, typical results of strain rate controlled strength tests of different geosynthetic reinforcements were summarized and discussed. Suggested low strain rate adjustments of various geosynthetics reinforcement materials were proposed as well. Results of this study are hoped to improve design and performance prediction of geosynthetic structures. For the covering abstract see ITRD E117244.
