Researchers in Duluth are trying new ways to fix the potholes by using powerful microwaves to heat the mix at the exact site where the craters developed, the Star Tribune said.
KTTC also reports that this technology they're experimenting with provides a use for taconite waste.
David Hopstock, a Roseville, Minn.-based consultant, told the Star Tribune that this technology could be the way potholes are filled in winter months in the near future.
Hoptock said it doesn't usually work in the winter because of how fast the mix cools off, he is worried about the road patched not lasting, according to KTTC.
KTTC reports that they will need to do more tests to see how long the patches last.
