(1977)<br>Giroud and Han (2004)</em></p><p>This FHWA design manual extends the use of a construction platform design analysis to permanent roadway applications. This method recognizes the additional support provided by the aggregate layer used in the construction platform as determined by either the Stewart et al.

<p><p><strong>Current FHWA Reference(s):<br></strong><em>Christopher and Holtz (1985)</em><strong>Supporting Reference(s):<br></strong><em>Haliburton and Barron (1983)</em></p><p>Halibuton Associates developed a design method, based on research by the US Air Force and the Nicolon Corporation, emphasizing the benefit of lateral restraint of the aggregate. This method is described in the FHWA Geotextile Engineering Manual (Christopher and Holtz, 1985), referring to a paper by Haliburton and Barron (1983).
