Robert D. Holtz, Professor, University of Washington


Title: Geosynthetics in Transportation Engineering--New Solutions to Old Problems
Many geotechnical and construction challenges associated with the design and construction of transportation facilities can be ameliorated by the judicious use of geosynthetics. Examples include drainage, filtration, and erosion control problems, poor subgrade conditions, soft embankment foundations, and unstable adjacent slopes. Geosynthetics in roads and highways is one of the oldest and most common applications of geosynthetics, and the primary focus of the lecture will be on their use for subgrade stabilization and drainage. The historical developments, subgrade conditions, functions, and benefits of geosynthetics in roadways will be briefly reviewed.  Then design procedures for both temporary and permanent roadways, material properties required, specifications, and pertinent construction details will be summarized.  Recent research including laboratory studies, forensic investigations, and the results of a 13-yr long study of a full-scale road test in Washington State will be also presented.
