| Abstract | This report synthesizes six topics related to geosynthetic reinforced soil (GRS) design: embedment length, pullout check, eccentricity, lateral pressures, the W-equation for GRS capacity and required reinforcement strength, and geosynthetic reduction factors. The synopsis for each topic includes a summary of the relevant research and a review of pertinent issues. The intent is not to provide recommendations but to explain the methodology behind the Federal Highway Administration’s (FHWA) composite design for GRS, which is different than that for geosynthetic mechanically stabilized earth. The synopses support the FHWA’s GRS Integrated Bridge System (IBS) Interim Implementation Guide, (FHWA-HRT-11-026). |
