| This thesis reports the results of two full-scale reinforced segmental soil retaining walls that were constructed and tested in the RMC Retaining Wall Test Facility. These walls corresponded to Walls 5 and 6 in a ten-wall test series. Both structures, which were constructed with a column of dry-stacked modular concrete facing units, were 3.6-m high, 3.3-m wide, and retained sand that extended approximately 6 m behind the wall facing. The first structure was reinforced with six layers of a knitted polyester geogrid that extended 2.52 m into the backfill soil while the second structure was reinforced with six layers of a welded wire mesh that extended 2.52 m into the backfill soil.;At the end-of-construction, both structures were subjected to staged uniform surcharging using a series of airbags confined at the top of the structure. The walls were loaded to stress levels well in excess of working load conditions and well beyond acceptable serviceability conditions. Both walls were heavily instrumented.
