Based on the findings of a runway roughness evaluation, the Omaha Airport Authority (OAA) determined the need for rehabilitating Runway 12/30.
Benesch’s design consisted of a three-inch mill and overlay of the existing pavement. Prior to the overlay, the existing concrete pavement was profile milled to correct smoothness, roughen the surface, and remove the existing joint sealant materials. Some isolated concrete panels were removed and replaced with new ‘high-early’ concrete in order to expedite the downtime of the runway for construction.
A new edge drain/subdrain system was also designed and installed as part of the project, along both outer longitudinal edges of Runway 12/30 to help drain the under sand base course. Temporary and permanent marking was also completed after the new asphalt overlay was constructed.
The Millard Airport is the busiest General Aviation airport in Nebraska and, with only one runway, the airport had to be closed to air traffic when the runway was under construction. Benesch worked closely with the OAA to formulate an aggressive time allowance in which contractors could complete the construction work and in turn limit the airport downtime. Coordination with several on-airport businesses had to be completed, since the shutdown of the airport impacted their operations as well.
