The National Concrete Masonry Association (NCMA) recently introduced a design manual for the analysis, design, and construction of geosynthetic-reinforced soil retaining walls that use dry-stacked masonry concrete units as the facing system. Important features of the manual are addressed, including methods of analysis, interpretation of long-term design strength of the geosynthetic reinforcement, selection of factors of safety, partial materials factors, and proposed test methods that address stability aspects of the facing system. Differences between current FHWA and AASHTO guidelines and the NCMA manual are discussed, and deficiencies in these earlier standards with respect to mortarless masonry wall systems are identified.
