Pavement Preservation Journal - Summer 2013 - (Page 17)

A five-year review completed in the summer of 2012 of a 2007 concrete pavement rehabilitation project in Colorado which involved grooving and grinding shows no further deterioration of the concrete pavement or ride quality. Bordering the eastern and southern sides of the Cargill Meat Solutions plant in Fort Morgan, Colo., Barlow Road and Gateway Avenue serve as the only route for continual 24-hour heavy truck traffic to move cattle and product to and from the plant. Because of the high level of wear developed over the years, a onemile long, four-lane-wide, segment of this roadway was in need of repairs. Nearly all of the road panels experienced faulting in both travel directions at an average panel displacement of 3/8 to 1/2 in. As a result, the bumpy riding surface was in need of rehabilitation. The heart of the problem existed within the design, which did not incorporate dowel bars at the transverse joints, and instead relied on base layers and aggregate interlock for load transfer. Unfortunately this design was no match for the extreme truck loading that this pavement received on a daily basis. The solution was base and sub-base stabilization, undersealing and alignment/lifting of concrete slabs, and diamond grinding with joint sealing. Each panel was lifted and leveled with the adjacent panel at the transverse joint by drilling a pattern of 5/8-in. holes on 4-ft. spacing through the pavement. Next, an expanding structural polymer from Uretek USA was injected to lift Concrete pavement restoration work in Fort Morgan, Colo., in 2007 and stabilize the surface. Diamond grinding was performed to smooth transverse joints and remove panel warping. The fi nal stepped included sealing approximately 35,000 linear feet of joints. The nondestructive methods used on this project eliminated the need to tear out the existing pavement, which saved time and money. By closing only one lane at a time, the roadway NEW 2013 BOARD FOR IGGA IGGA—a non-profit organization dedicated to serving as the leading promotional and technical resource for acceptance and proper use of diamond grinding and grooving, as well as pavement preservation/ restoration—elected new board members and officers for 2013. New president is Tom Bonness, Jr. of C.P.R., Inc. Following more than 25 years’ experience in the concrete paving industry, Bonness has specialized in concrete pavement repair, full and partial depth repair and dowel bar retrofit techniques. Bonness began as a skilled laborer, IGGA was able to safely remain open full time to local traffic, with all lanes available for use between project work shifts. The result was a largely greatly improved, smooth and safe ride that is expected to extend the life of the pavement by 20 years. With a total project value of $643,000, the taxpayer cost was estimated at 50 percent of the cost to remove and replace. and now is the president of C.P.R., Inc., a concrete contracting company based in Elkhorn, Wis. He also is managing member of C.P.R. Leasing, LLC and the president of T3 Concrete Testing, Inc. Other new officers include vice president, Jake Steinberg of Construction Materials, Minneapolis; secretary, Terry Kraemer of Diamond Surface, Inc., Rogers, Minn.; treasurer, Scott L. Eilken of Quality Saw & Seal, Bridgeview, Ill.; past president, Alex Ugalde of Hilti North America, Tulsa; director, Jerry Voigt, American Concrete Pavement Association, Rosemont, Ill.; and international director Charley Grady of Crafco, Chandler, Ariz.
