Project Summary

In the summer of 2009, ADOT&PF applied dust-control palliatives to nine rural airport runways across Alaska. AUTC researchers will monitor these runways to assess palliative quality and durability. Measurements are taken with the UAF DUSTM, a portable instrument that measures lofted dust as it rises from the rear tires of an all-terrain vehicle. Palliative performance will be assessed by comparing the measured fraction of lofted dust produced by the ATV on the treated section of the runway to the fraction produced on the untreated control section. Researchers took measurements within 30 days after the first treatment on each runway, they will follow up with another measurement one year later. Recommendations will help ADOT&PF select the most effective product out of several and plan the most efficient application schedule for Alaska's many unpaved runways.

No final report required for this project. Inspection records turned over to DOT&PF per contract.
