<p><p><h2>Preferred Design Procedure</h2>There are two preferred geosynthetic-reinforced pavement design procedures acknowledged by the FHWA Geosynthetic Design and Construction guidelines. These methods are the Empirical Design Method and the Mechanistic-Empirical Design Method. The Empirical Design Method is based on AASHTO (1993) Guide for Design of Pavement Structures and AASHTO (2001) Geosynthetic Reinforcement of the Aggregate Base Course of Flexible Pavement Structures – PP 46-01.</p><p>The Mechanistic-Empirical Design Method is a new design method adopted by the AASHTO (2008) Mechanistic-Empirical Pavement Design Guide (MEPDG), Interim Edition: A Manual of Practice. This design method is not associated directly with geosynthetic reinforcement in pavements. However, it has been shown in studies (Perkins et al. 2009, Kwon et al. 2009) that the MEPDG can be modified to reflect the strength and durability gained by geosynthetic reinforcement in pavements.</p><p>The Federal Highway Administration (FHWA) has a set of design documents for this technology. The documents are summarized below.</p><p><table class='tablepress' id='tablepress-300'><thead><th><center>Publication Title</th><th><center>Publication
