Southeast Iowa Regional Airport, Runway 18-36 Reconstruction
Burlington, IA
The Southeast Iowa Regional Airport tasked McClure with providing design, bidding, and construction support services for the rehabilitation and reconstruction of its primary runway, Runway 18-36. The runway consisted of an approximately 6-inch-thick asphalt surface course placed over an 8 to 10-inch-thick concrete pavement. Most of the concrete dated back to 1944, with a 1,351-foot extension added to the south in 1968. The most recent improvement prior to the project was a 3-inch asphalt overlay completed in 2005.
At the time, the asphalt surface was exhibiting climate-related deterioration, including cracking, weathering, and blowups—particularly along the edges of the runway. A visual pavement assessment conducted in 2014 assigned a Pavement Condition Index (PCI) rating of 59 out of 100 to most of the runway, while the southernmost 1,000 feet was rated at 56. During the preliminary design phase, a geotechnical investigation confirmed the need for full reconstruction of the runway to restore its structural integrity and long-term performance.
The project encompassed eight key elements aimed at improving the safety, functionality, and longevity of airfield infrastructure at the Southeast Iowa Regional Airport. These included the full reconstruction of Runway 18-36 and the regrading of its safety area to enhance drainage and meet current FAA standards. The existing displaced threshold on Runway 18 was removed, and a new Taxiway A1 was constructed to provide direct access to the existing Runway 18 threshold. Runway 12-30, located within the Runway 18-36 Object Free Area, was also reconstructed. Additional improvements involved the reconstruction and rehabilitation of various taxiways across the airfield. The project also included upgrades to navigational aids (NAVAIDs) and visual aids to support safe and efficient aircraft operations. Lastly, a temporary displaced threshold was implemented on Runway 18 during construction to maintain operational continuity.
