SPR-5026: Evaluating the Effectiveness of Geosynthetics in Controlling the Detrimental Effects of Slow-Moving and Turning Traffic

This study presents a comprehensive evaluation of geosynthetics in slow-moving and turning traffic regions. Phase 1 includes laboratory testing to assess geogrid effectiveness by quantifying lateral restraint, and stiffness enhancements under turning traffic stress conditions. Phase 2 focuses on field implementation with site selection, instrumentation, and in-situ performance monitoring. The study will develop optimized design strategies and construction practices, with findings disseminated through a final report and implementation guidance for effective integration into INDOT projects.
