Comparison of ASTM Standards for the Evaluation of Geogrid Strength
| 项目名称： | Comparison of ASTM Standards for the Evaluation of Geogrid Strength |
| 摘要： | This study would be focused on geogrid tensile strength. This parameter is used by WisDOT engineers in the design and specification of geogrids in reinforced soil structures. The Wisconsin Department of Transportation (WisDOT) currently specifies the ASTM Standard D4595 �Standard Test Method for Tensile Properties of Geotextiles by the Wide-Width Strip Method� to measure the tensile strength of geogrids. However, this specification was developed for the use on woven geotextile fabrics and not for geogrids. In recent years the geogrid manufacturers have utilized the ASTM standard D6637 �Standard Test Method for Determining Tensile Properties of Geogrids by the Single or Multi-Rib Tensile Method� in place of ASTM D4595 for determining tensile strength. The desired research outcomes would include a comprehensive study that assesses the testing mechanics, compares the results obtained with the two methods, and provides a correlation that would allow WisDOT to migrate from ASTM D4595 to ASTM D6637 in determining tensile strength of geogrids. These results are needed so WisDOT design engineers have the confidence in using the new standard for the design and specification of geogrids for the construction of earth reinforcing structures, reinforced earthen embankments and subgrade stabilization in transportation facilities. |
