The Minnesota Department of Transportation has released a technical brief that determines effective methods for stabilizing damaged roadway slopes. These methods could be used for local non-geotechnical engineers (ie. maintenance personnel) to identify the type of slope failure and then select an appropriate repair method. In addition, the methods can help determine whether slope damage repair can be completed by local engineers or if outside help is needed. Certainly, as a geotechnical engineer, I think this approach makes me a little concerned. But I understand the financial and logistical constraints for smaller municipalities and rural communities. When in doubt, I hope they confer with a geotech!
The Washington State Department of Transportation has released a report that provides a reference for geotechnical engineers and hydrogeologists on designing horizontal drainage systems to improve slope stability. Here’s the report abstract: The presence of […]
