Unalakleet Airport Paving Temporary Runway
Centerline Stripe

Temporary runway stripe overview

• The Department recognized a need to improve
  positive guidance to pilots during partial
  closures of runways under construction.
• The Unalakleet Airport Paving project utilized a
  temporary runway centerline stripe on the
  half-width crushed aggregate surface.
• This was very well received by the users. We
  recommend use of a temporary runway centerline
  stripe on all applicable projects.

The Unalakleet Airport serves as a regional hub
for the Eastern Norton Sound.
A temporary centerline stripe was painted on the
75 wide half-width aggregate surface added by
change order.
4
There were approximately one jet, five turbo
props and thirty small engine plane landings a
day. The stripe lasted about a week, with the
jet traffic being the limiting factor.
Temporary stripe life would be much longer in the
absence of jet traffic.

The total 2008 temporary stripe cost was 30K
which is similar to the costs of
temporary stripes on highway projects. Bid
prices would be expected to be lower than the
change order price.

The striping was done with a walk-behind paint
machine using oil based white paint (22W-D010-C08-
White Acrylic Low Voc Zone Marking Paint) at an
approximate spread rate of 10-15 gallons per
centerline stripe (120 skip 80 12 inch
width).

The surveying and striping work took
approximately 2-3 hours each stripe and re-stripe.

The users expressed delight in the Departments
efforts. It took the guess work out
of determining where they needed to land. They
easily saw the stripe from above and knew where
to land safely. No incidents were reported.

We highly recommend that a Temporary Runway
Centerline Stripe be added to all Future aviation
projects where applicable.
