HIGHWAY ROCK SLOPE RECLAMATION AND STABILIZATION, BLACK HILLS REGION, SOUTH DAKOTA, PART I, REPORT. FINAL REPORT

Numerous constructed rock slopes along highways traversing the Black Hills region require considerable maintenance every year. Many of these slopes are steeply inclined and are susceptible to the effects of erosion and possible instability. The objectives of the study are to (1) categorize existing constructed rock slope conditions in the Black Hills, (2) evaluate treatment methods presently used in the Black Hills, (3) evaluate other treatment methods with respect to Black Hills conditions, (4) develop site-specific rock slope treatment methods for several specific Black Hills rock slopes, and (5) develop recommendations for improving rock slope stability and provide guidelines for cost-effective implementation of those recommendations. The report provides recommendations for treatment methods for sites identified by the South Dakota Department of Transportation (SDDOT) and also provides "problem-specific" guidelines for selecting treatment methods that may be applied to other sites. Twenty-five study sites were selected from highway sections identified by the SDDOT, which include sections of US85, US385, US16, US16A, and SR71. The sites were selected to give a representative cross section of cut slope performances. Rock and soil units represented in the 25 site studies are grouped into six categories based on rock and soil engineering characteristics, slope failure mechanisms, optimum stable slope ranges, and applicable slope treatment methods. The report consists of two parts, each bound separately. This part, Part I, provides a detailed discussion of the site conditions, research methods and results, and suggestions for continuing studies; the Appendix to Part I contains information and photographs compiled during field reconnaissance for the 25 study sites. Part II of the report provides a detailed discussion of the "problem-specific" guidelines, and references; the Appendix to Part II contains blank site reconnaissance forms and examples of completed forms.
