The study involved in-isolation and in-aggregate laboratory testing of severla base reinforcement geogrid products from major geosynthetic suppliers. In-isolation tests included rib strength and junction strength tests, and in-aggregate tests included pullout and plate load tests. Field-scale installation damage tests were also performed. Test results on different geogrids in this study were aimed to quantify the significance of the geogrids in-isolation properties on their in-aggregate response under controlled conditions.210 pages13,960,085 bytesapplication.pdfTechnical ReportGeogridpavementaggregatestrengthpullout testcyclic plate load testinstallation damage
