Title	Development of ODOT guidelines for the use of geogrids in aggregate bases
Authors	Oklahoma. Department of Transportation. Hatami, Kianoosh. Mahmood, Tahsina. Zaman, Musharraf. Ghabchi, Rouzbeh. University of Oklahoma. School of Civil Engineering and Environmental Science.
Publisher	Oklahoma Department of Transportation
Publication Date	2012-03
Publication type	Research Report/Study
Subject	Geogrids. Pavements--Subgrades. Geogrids--Testing.
Purpose	It has been shown that geogrids, when properly installed as aggregate base and/or subgrade reinforcement, can help to improve the service life and performance of roads and highways and help reduce their repair and maintenance costs; The existing specifications manual of the Oklahoma Department of Transportation (ODOT 2009) only endorses a very limited number of geogrids for base reinforcement and needs to be updated to include a wider range of products that are currently available on the market. However, there are currently no universally accepted guidelines for the acceptance and specification of geogrids for base reinforcement and subgrade stabilization applications.; Therefore, a primary objective of the current study was to help ODOT expand its selection of approved geogrid products for base reinforcement applications by producing measured data on selected geogrids and a dense-graded base aggregate commonly used in ODOT roadway projects.
