What are geogrids?

Geogrids are materials that have openings, called apertures, which allow aggregate to strike through and provide confinement and interlock. Geogrids can improve the long-term performance of a roadway by minimizing aggregate movement and maintaining modulus values. In order to properly introduce a specific geogrid into the M-E model, appropriate characterization of the aggregate-geogrid composite layer that is created through a mechanical stabilization process is required. Significant product specific calibration and testing is required over differing conditions and materials to understand the impact of a Mechanically Stabilized Layer (MSL) on stresses, strains and deflections within a pavement section, as well as its effects on pavement distress. The contribution of geogrid material into a pavement structure can be very difficult to accurately define using conventional testing equipment and standard construction practices due to the lack of a conditioning stage prior to testing.
