• Abstract:
  White pavement paint marking on airport runways was being discolored by rust-like staining. Discoloration is a critical safety ; problem because white paint indicates runways and yellow paint is used for taxiways and aircraft parking. When the white paint is ; stained it becomes more difficult to distinguish from the yellow paint. This study determined the cause of the discoloration was ; from the ferrous minerals found in the pavement aggregates. ; The study included contacting the industry for methods to extend the service life of pavement paint markings. Water blasting the ; paint to remove the rust and/or using a modified Federal Specification TT-P-1952E water-borne paint has proven to mitigate the ; staining. In addition, staining can be reduced by applying a protective coating over the paint; pretreating the asphalt; or using ; alternative pavement marking materials. Life-cycle cost analyses identified the modified Type III water-borne paint with Type III ; beads to be the least costly of the proven and potential methods presented
