This report gives the results of the investigation of twenty projects exemplifying the use of geotextiles by the Alaska Department of Transportation and Public Facilities. These projects fall into three categories: subdrainage and riprap liners, embankment separation and reinforcement, and paving overlays. The report is introduced with a status of geotextiles manufacture and design followed by a description of geotextile properties. Each section begins with a discussion of the principles for the use of geotextiles which is followed by the case histories. Based on the experience gained in the case histories and existing literature, recommendations for the use of geotextiles are represented along with recommended specifications. The report concludes in saying that the use of geotextiles in Alaskan engineering will continue to grow as designers become more familiar with existing design techniques and as research learns about the functions of geotextiles.
