EXPERIMENTAL CONCRETE GOES BAD ON HIGHWAY PROJECT

More than a half-mile (0.8 km) of experimental pavement poured as part of a $1.8 million repaving of state highways north of Willmar, Minnesota, was torn up after developing about 115 unexplained cracks. The concrete was a mix of recycled fly ash and steel slag. Random cracks developed in the 2,700 ft (823 m) of concrete shortly after it was placed. The concrete will be tested by the Minnesota Department of Transportation and laboratories for the contractor and supplier.
