Project Engineer Matt Majoros, PE and Geotechnical Engineer Brian Mullen, PE presented to the University of Alaska Fairbanks Student Section of the American Society of Civil Engineers on April 20th about the Nome Airport Rehabilitation Project.
This project rehabilitated Runway (RW) 03/21 and RW 10/28 at Nome Airport. It included installation of a unique deep ground improvement system to mitigate long-term settlement issues plaguing the west end of RW 10. More than 1,200 steel pipe piles bearing on bedrock and a load transfer platform were installed at depth below the embankment in the settlement areas to act as a bridge/support structure for the runway. The entirety of both runways were rehabilitated with new pavement and foamed asphalt stabilized base course. The project also widened and paved shoulders for RW 03/21, repaired a deep crack at RW 28, repaved the Aircraft Rescue and Fire Fighting apron, replaced RW lighting, and grooved and marked the runways. Construction was completed Fall 2022.
Matt was the lead civil engineer and Brian the lead geotechnical engineer on this project.
The two-part presentation covered the: 1) overall airport rehabilitation project and 2) the pile-supported embankment that was installed as part of the wider project to solve settlement issues. Matt covered part 1, talking about the project background, design and construction. Brian covered part 2, discussing the pile supported embankment solution.
