Project description

This research will employ state-of-the-art methods, i.e., automated plate load testing (APLT) and bender element (BE) field sensors to directly measure geosynthetic reinforcement stiffness improvements to base and subgrade layers. Testing results will be used to develop geosynthetic reinforcement design guidelines for Indiana Department of Transportation (INDOT) pavement design (e.g., recommended resilient modulus values due to geosynthetic reinforcement and the related mechanically stabilized base course modulus profile with depth, optimum geosynthetic layouts, Mechanistic-Empirical Pavement Design Guide (MEPDG) implementation, etc.).
