Allowable Stress Design (ASD)
<p><p><strong>Current FHWA Reference(s):<br></strong><em>Berg et. al (2009)</em><strong>Supporting Reference(s):<br></strong><em>AASHTO (2010)<br>Tanyu et. al (2008)</em></p><p>The overall design requirements for Reinforced Soil Slopes (RSS) are similar to those for unreinforced slopes: A limit equilibrium, allowable stress approach is used and the factor of safety must be adequate for both the short-term and long-term conditions and for all possible modes of failure.
