CPAM Hosts Tour of Iowa Overlays

The Concrete Paving Association of Minnesota (CPAM) hosted a “Tour of Selected Iowa and Minnesota Highways” on November 6, 2014.   This tour was a repeat tour from 2007, with some new additions.  This year’s tour consisted of 14 personnel from Minnesota counties, one representative from the MnDOT State Aid Office, the Worth and Mitchell County (IA) Engineer, one staff member from the Iowa Concrete Paving Association and three staff members from CPAM.

The 2007 tour visited five concrete overlay projects ranging in construction dates from 1983 to 1993.  Upon returning to these road sections in 2014, two of the road sections were still rated as smooth and the others were noted as “choppy” and “a little faulted” with some minor cracks.  Rich Brumm, Worth and Mitchell County Engineer, indicated his section (Mitchell County T38) is now ready for diamond grinding to smooth out the ride since the panels are not moving under the traffic loads.

Three additions were made to the tour for 2014, which included overlays (one in Minnesota) with thicknesses ranging from 4 to 5 inches thick, and were constructed between 2009 and 2014.

The intent of this tour was to demonstrate the performance history of concrete overlays.  Although some of the older sections are now showing signs of some repair needs, these overlays continue to stand the test of time with little to no maintenance over their 20- to 30-year history.   Please contact CPAM with any questions.  View the complete report here.
