The objective of the study was to validate the performance of blocked-faced Geosynthetic Reinforced Soil (GRS) wall and to validate the Colorado Department of Transportation's (CDOT) decision to waive the positive block connection for closely-spaced reinforcement. Contrary to conventional wisdom, the GRS wall measurements of this study demonstrated that facing pressure decreases as load increases. This counter-intuitive fact is due to the decrease of compaction-induced stress (CIS) with increased load. Therefore, if a GRS wall survives compaction, it survives indefinitely., Peter Hoffman, Jonathan Wu., Performing organization name: University of Colorado Denver, Department of Civil Engineering., Included bibliographic references., Report No. CDOT-2017-3, Online resource; title from PDF cover (viewed August 2019)
