Note: An alternative method for designing geosynthetic walls allowed in AASHTO 2020 is based on limit equilibrium (LE).AASHTO 2020 – Simplified Stiffness Method for geosynthetics which can be used instead of the Simplified AASHTO.Simplified AASHTO Method for geosynthetics and metallic reinforcement as well as an option for using Coherent Gravity Method for metallic. FHWA-NHI-10-024 (as related to traffic barrier load and some of the bridge abutment methodology).MSEW+ is an interactive program for the design and analysis of mechanically stabilized earth walls.
