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.


For more than 30 years, Tensar’s innovative ground stabilization solutions have proven ideal for many kinds of construction and subgrade improvement projects, including paved and unpaved roads, parking lot, airfields, heavy duty pavements and working platforms. We also offer full technical support including design software, expert advice and site assessments.
