b'Pavement Issues One of the biggest challenges was that Runway 14-32 had different types of pavement structures installed at different times. The original runway was concrete, but various layers of asphalt overlays had been applied in various sections throughout the years. The geotech analysis we did before construction found a lot of irregularities, McMichael reports. We wanted to make both the runways and taxiways a consistent strength and surface, and we made sure we met FAA specifications on pavement surfaces throughout the project.The Construction Safety Phasing PlanDelpatch Elastomeric Concretedivided the project into several phases, withPrimary Applications:contractors starting on the north/14 end.Partial Depth Spall Repair | Airfield Lighting RetrofitPart of the work consisted of enlarging the PermanentEasy blast pad to current FAA requirements, which required excavation and installing additional SafeFast pavement.

In the past, all electrical circuits had been done piecemeal, says Worley. During construction, the contractors occasionally found old cables. They were not sure if they were live or not, or what they were used for. Fortunately, most of them were abandoned and not energized.We have now created a much safer environment, he adds. We have a user- Meets FAA P604 ASTM D 2628 & CRD-C 548friendly map showing the wiring of allelectrical systems and LED lights, and itLongest Lasting Joint Sealshows which cables connect to which lights.

I think we had excellent teamwork from all parties involved to accomplish this on schedule and on budget. dsbrown.com | 419-257-3561 | AirportImprovement.comMay | June 2022'
