<p><p><h2>Preferred Design Procedure</h2>The Federal Highway Administration (FHWA) has design guidance for this technology. The design document also contains information about construction techniques, quality control/quality assurance, and specifications. Chapter 6 of the document contains the complete design procedure. A summary of the procedure is presented following the reference table below.</p><p><table class='tablepress' id='tablepress-296'><thead><th><center>Publication Title</th><th><center>Publication
