A two-course overlay of existing concrete, this 4-mile long project spanned M-59 from I-75 to Crooks Road, a heavily traveled commuter route. During the ﬁrst phase, we discovered the concrete was in worse shape than anticipated, increasing the concrete patching and asphalt repair work almost tenfold.
Prior to placing the leveling course of asphalt, a substantial asphalt wedge course — up to 8 inches deep — was placed to bring the cross slopes and super elevated sections up to Michigan Department of Transportation standards. A total of 3.5 inches of asphalt was placed over the entire freeway. More than 120,000 tons of asphalt was manufactured at the Crooks Road Plant for this project.
