SH 20 Keetonville Hill Landslide Repair Rogers County, Oklahoma

This paper presents the concluding remarks of a landslide repair project that was completed in May 2008. The scope of the repair project involves the Oklahoma Department of Transportation’s (ODOT) history dealing with this site, a limited site investigation, the development of a repair solution, construction details and changes, and a detailed post slope stability analysis. There was no time allotted for a proper geotechnical investigation and slope stability analysis again per the instruction of the ODOT administration staff and Director. The site investigation consisted of an afternoon walkout of the landslide on April 10, 2008, and repair solution was to be presented the next morning to the emergency scoping team. The scoping team included key personnel from the field Division 8 Construction Division and central Oklahoma City Survey, Roadway Design, Bridge, and Materials Divisions. A total of twelve borings were allowed with the essential effort of assisting the contractor. No inclinometers to monitor the repair performance were authorized. ODOT had investigated this landslide in 1983, 1994, and 1995 through the ODOT Geotechnical Branch in the central office Materials Division. Division 8 had elected to make only temporary maintenance following these previous slope failures. The Geotechnical Branch had experience with the site soils and geology from their previous studies.
