Somewhere Between Super and All-Star: Michigan DOT's Decision to Go With Concrete Overlay Produces Great Results

In this article the author discusses the Michigan Department of Transportation's (MDOT) implementation of concrete overlays on Gratiot Avenue in Detroit. The 198,000 square yards of pavement is of note for concrete overlay projects as the overlay way placed atop a concrete pavement base, whereas typically these overlays use an asphalt base. The project, which was completed in just one season and cost a total of $7.17 million, involved a number of agencies and private companies due to the complexity of using concrete overlay over a concrete substructure. Once the cold milling of the damaged base was complete, the base's stability was checked and it was found that the estimated repairs exceeded what was actually needed. Construction was complicated by the existence of trolley rails within the roadbed, which constructors found using a ground penetrating radar (GPR).
