Willow Run Airport
Pavement Condition Study

The Willow Run Airport in Ypsilanti, Michigan was once the manufacturing center for the B-24 Bomber. Currently this 60-year old facility is a major hub for air cargo in Southeast Michigan. The Program Managers Team, L.L.C. retained NTH to implement a Pavement Management System (PaMS) for 6 runways and 10 taxiways, totaling 4 million and 3 million square feet of pavement, respectively.

Project Approach
Following PCI methodology, we:
  • Developed a baseline inventory and condition assessment, utilizing an existing map, CAD, and digital aerial photography.
  • Divided pavement components into a series of distinct branches and sections, developing an inventory of each.
  • Performed visual surveys in accordance with the Standard Test Method for Airport Pavement Condition Index Survey, compatible with the PAVER software program.
  • Developed a quality assurance verification program to review data.
  • Reviewed agency records for traffic data, maintenance history, construction cost data and other pavement elements.
  • Used a Differential GPS Data Collector for on-site referencing of field test locations, incorporating data from this system into the GIS dataset.
  • NTH coordinated non-destructive testing of the facility’s 5 active runways and 10 taxiways.
​
Project Results
NTH utilized the PAVER software program to:
  • Evaluate the current condition of each pavement section
  • Estimate future performance characteristics
  • Develop prioritized maintenance and repair strategies
  • Develop a multi-year, network-wide pavement maintenance work plan, with prioritized maintenance and repair strategies
