In this study, we aimed to verify the behavior of geosynthetic-reinforced pavement systems through large-scale rolling wheel tests performed with problematic subgrade soils. Large-scale specimens that mimic an aggregate base–geosynthetics–subgrade system were constructed on different subgrade soil conditions at the University of Georgia Pavement Research Facility in the U.S. Both an extruded biaxial geogrid and woven geotextile were placed on various locations in the aggregates and subgrades to investigate the optimal placement location through pressure sensor measurements. The results of this research indicate the effects of different subgrade conditions, geosynthetic reinforcement type, and geosynthetic placement location on the pressure experienced by pavement layers and the changes in stiffness of the aggregate base course.View this paper.
