Alternative laboratory approach for determination of geogrids performance in mechanically stabilized layers

Abstract

New laboratory plate test method is proposed for the determination of geosynthetics performance and efficiency of the interlocking in mechanically stabilized layers. The laboratory equipment and experimental methodology are described in details. Proposed method was tested in a set of trials which are evaluated in the paper. Resulting methodology is based on matrix type of tests evaluation, the matrix is formed by several measured parameters. Experiments executed in the laboratory confirmed that the principle of the method is correct and the methodology can be applied for geogrid performance evaluation of various geogrids.
