Benesch completed a Pavement Condition Index (PCI) study for the Lincoln Airport’s (LNK) Runway 18/36, which identified the need for asphalt rehabilitation. After completing additional assessments of the runway’s existing conditions, Benesch developed design plans for the outer edges of the runway asphalt with as-needed concrete repairs to its 100-foot-wide center keel section.
The project consisted of a nine-inch mill and overlay directly adjacent to the center concrete keel, with the remaining asphalt pavement receiving a four-inch mill and overlay. For the center concrete areas, new 15-inch thick isolated panel replacements, partial-depth patches, and joint and crack resealing were completed.
The project involved close coordination with LNK and the FAA Central Region, in addition to the Nebraska National Guard, Lincoln Wastewater System (LWS) and Lincoln Electric System (LES).
Because Runway 18/36 is the airport’s only Instrument Landing System (ILS) runway, leveraging the time between shutdown and re-opening were critical to LNK operations. Coordination efforts with LWS and LES allowed these utilities to complete major work on adjacent improvement projects during the runway shutdown.
