SPR 12-437 Guidelines for geotextile and Geogrid Use on Highway Projects

In recent years, several issues related to geotextile and geogrid in Kentucky use on highway projects have been identified. These include: 1) Development of the appropriate specifications for geogrids and geosynthetics. 2) Development of usage guidelines for both geogrids and geosynthetics. The objectives of this research will be as follows: 1) An in-depth review on current specifications and usage guidelines used by other Departments of Transportation nationwide. 2) Development of a user guide for both geotextiles and geogrids to assist design engineers, specification writers, construction inspectors and maintenance personnel with the selection, design and construction of geotextile and geogrid involved projects.
