Concrete overlays for long-term durability in Minnesota

To rehabilitate distressed roadways in Minnesota, McLeod County decided to use concrete overlay. Concrete that is 12.5 cm (5 in) thick was paved over the top of a milled asphalt surface on this 12-km (7.5 mi) project using our Type I/II cement. The new highway is economical, bright and safe, and provides long-term durability.
