Full-scale test sections were constructed and trafficked at the U.S. Army Engineer Research and Development Center (ERDC) to provide performance data comparing the effectiveness of multi-axial geogrid stabilized flexible pavement sections to an unstabilized flexible pavement section. Two test sections containing differing multi-axial geogrids were constructed and trafficked under shelter in ERDC's Hanger 2 Pavement Test Facility. The test sections were subjected to accelerated traffic loading using a dual-tandem axle configuration simulating typical highway loadings. Permanent surface deformation, rutting, pavement stiffness, and instrumentation response data were collected at designated traffic intervals. The results of the study indicate that the geogrid stabilized sections improved the performance of the pavement section when compared to the unstabilized section.
