<p><p><h2>Preferred Design Procedure</h2>There are multiple design/analysis procedures for geocell confinement in pavement systems including those presented in Mengelt et al. (2000), Pokharel (2010), Presto Geosystems (2007), and Yang (2010). The design/analysis procedures are validated to a limited extent and further validation and/or improvement of these procedures is needed. Table 1 shows typical inputs and outputs for analysis and design procedures for this technology.</p><p>The Federal Highway Administration (FHWA) does not have any design guidance documents for this technology. The available design/analysis procedures are discussed below:</p></p>
