Are Current Rigid Pavement Roundabout Designs Working in Minnesota?Status: ActiveProject Start Date: No DateSubscribe for Updates Summary: Rigid pavement roundabouts were initially designed with the expectation that they would experience distress similar to rigid pavements designed and built on motorways. However, distresses will occur differently due to the way traffic loads interact with them, the shape of panels, and drainage. The objective of this research is to provide guidance documentation for both MnDOT and local agencies to improve roundabout designs for better long-term performance and reduced future costs in the maintenance and rehabilitation of these assets.
