This study willfocus on developing newer (innovative) approaches to evaluate slope failures andprovide cost-effective repair and mitigation techniques. Typically slides are repaired byexcavating the slide material and then backfilling with more stable material. However,MoDOT is looking for the researcher to review newer more innovative techniques thathave been deployed nationally by other State Departments of Transportation,Geotechnical journals, Geotechnical contractors and any organization that is responsiblefor the repair of landslides. The goal is to find repairs that provide for long-termstabilization, but that are more cost effective than the typical excavation method. Theresearch is to develop a listing and description of these innovative slope repairtechniques. The study shall provide MoDOT with descriptions of when these innovativetechniques could be deployed and what are the resources, materials, equipment andpersonnel needs required to accomplish such repairs
