Kentucky Transportation Center Research Report
Two test methods have been developed in this project. The first test method is a compression test of a cylinder constructed out of geogrid material and filled with crushed stone. This test is simple and can be easily performed. Only a compression loading machine is needed for this test. The sample preparation is straightforward. However, multiple tests must be run to analyze geogrids with different ultimate tensile strength or different grid aperture size on machine direction and cross machine direction. The second test method is Geogrid Bearing Ratio (GBR) test. This test was developed to measure the effect of geogrids …
