New Report: Taconite-Based Mixture Shows Further Promise for Repairing Potholes

March 8, 2020 by Shannon Fiecke

Researchers have further refined a quick and innovative pothole repair method using taconite mixtures.

The recently completed study was funded by the Minnesota Local Road Research Board in collaboration with MnDOT, the City of Duluth, and the Duluth International Airport. Researchers evaluated the performance of taconite repairs completed in 2018-2019 and developed a new two-ingredient mixture. The mixture shows promise as a cost-competitive, long-term solution for potholes.
