Best Practices for Pavement Design Using Geosynthetics

Sunday, January 07, 2018, 1:30 PM-4:30 PM, Convention Center 2018
Jie Han, University of Kansas; Jennifer Nicks, Federal Highway Administration (FHWA); Erol Tutumluer, University of Illinois, Urbana Champaign, presiding
Sponsored by Standing Committee on Geosynthetics; Standing Committee on Aggregates; and Standing Committee on Subsurface Drainage

The benefits of including geosynthetics in the design of transportation infrastructure have been widely recognized. For pavement applications, geosynthetics have been used for mechanically stabilizing aggregate bases over weak subgrade through lateral restraint or used for pavement drainage including underdrains and edge drains.  The geosynthetic products used for pavement applications include geotextiles, geogrids, geocells, geonets, and geocomposites. Considerable research efforts have been performed, along with case studies from many transportation agencies that serve as a basis for disseminating knowledge on the best practices for pavement design using geosynthetics. This workshop is expected to attract geosynthetics, hydraulics, and pavement design experts, researchers, and practitioners.
