In Situ Testing Informed Sublayering Approach for Mechanistic Analysis and Design of Geogrid-Stabilized Pavement Foundations

This study introduces a sublayer-based modeling approach to characterize the stress-dependent modulus behavior of pavement unbound aggregate layers stabilized using geogrids. Current modeling and design approaches either apply a higher uniform layer modulus or disregard geogrid stabilization benefits. A uniform increas...
