Optimizing Bridge Abutment Slope Protection at Stream Crossing

Project: Research project

Project Details


The following specific objectives are defined based on the request for proposal (RFP) by WHRP:  Determine the severity, causes, and types of slope protection issues in Wisconsin by analyzing qualitative and quantitative factors believed to trigger failure in the slope protection.  Plan and oversee comprehensive surveys providing useful information about alternative slope protection strategies practiced successfully at various other states.  Perform Life-Cycle cost analyses to provide information about the optimum abutment slope protection strategy with maximum service life and minimum life-cycle cost.  Update the WisDOT bridge manual with consistent recommendations and guidelines from this study.
