About this file
The document is an Airfield Pavement Management Program Update for 2025, prepared by RS&H for the Cincinnati/Northern Kentucky International Airport (CVG), focusing on Taxiway M East. The report provides a comprehensive assessment of the taxiway's pavement condition, including surface area breakdown, structural composition, and condition indices. The taxiway consists of 382,000 square feet of concrete (73%) and 144,000 square feet of asphalt (27%), with an additional 333,000 square feet of asphalt shoulder area.
The Pavement Condition Index (PCI) survey reveals that the taxiway is currently in good or satisfactory condition, though maintenance efforts will need to increase to prevent significant deterioration. Primary distresses include linear cracking, patching, and spalling on concrete surfaces, and patching, cracks, and block cracking on asphalt areas. The Pavement Classification Rating (PCR) is 540/R/B/W/T, with 10 aircraft in the fleet mix exceeding this rating. The two aircraft with the highest annual departures that impact the PCR are the B737-900 and B767-200. The report suggests that without rehabilitation or reconstruction, the pavement's condition will significantly decline in the future, necessitating ongoing maintenance and potential future infrastructure investment.

Pavement Condition Index (PCI) Results The PCI values shown below for Taxiway M east are in either Good or Satisfactory condition. During the PCI survey, the results of extensive airport maintenance efforts were observed since the previous PCI survey was conducted in 2022. Due to this effort, the PCI results appear to be good; However, while preserving the immediate life of the pavement to ensure safe aircraft operations, the maintenance efforts required maintain this area will continue to increase and the PCI values will begin to significantly drop in the future without a rehabilitation or reconstruction effort due to the significant amount of distresses that include linear cracking, patching, and spalling on concrete areas, patching and cracks on asphalt areas, and extensive block cracking on the shoulder areas.

Pavement Classification Rating (PCR) Results The PCR for Taxiway M is 540/R/B/W/T. There are 10 aircraft in the fleet mix used that exceed the PCR. Most have relatively low annual departures, but the two most that have the highest annual departures are the B737-900 and B767-200. Those two aircraft are reflected in the red spike in the graph below.
