The main runway at Paine Field is getting extra attention from airport staff after recent maintenance work has left it at times with less surface traction than required.
Because of this, the runway was closed late July 11 and reopened the next morning. The closure came after Paine Field staff noticed slick conditions during an inspection of the runway surface.
Airport operations and maintenance crews have since been conducting friction tests to make certain conditions remain safe. The 9,010-foot runway could be closed again if necessary.
The runway underwent maintenance from July 1 to July 8. The work, which required the runway to be closed, included application of fog seal treatment to about 1.2 million-square-feet of its surface.
Airport staff have had ongoing conversations with design engineers, the product manufacturer, construction managers and others. Experts from the Federal Aviation Administration also are being consulted.
The experts believe warm temperatures and time will allow the product applied the runway to properly “cure,” restoring consistent friction. Additional work may be necessary, including potential closures.
The planned maintenance work was necessary to maintain the runway’s integrity and prolong asphalt life.
