RECOMMENDATION
Recommendation
That Council adopts the attached resolution (Attachment I) approving the plans and specifications for the Runway 10R-28L Rehabilitation Project at Hayward Executive Airport project, calling for bids to be received on May 17, 2016.
Body
BACKGROUND
As previously presented at the Council Airport Committee meeting on January 22, 2015, rust resulting from the oxidation of iron minerals in the pavement aggregate is penetrating through the existing runway markings on Runway 10R-28L at the Hayward Executive Airport. This has reduced the contrast between the dark pavement and white paint markings and could create potential unsafe conditions for aircraft using the runway. This project calls for the rehabilitation of the main runway. The proposed improvements will remove the top two inches of oxidized pavement that will be replaced with new asphalt pavement. By carefully testing the new asphalt to confirm that it meets standards, we do not expect a reoccurrence of this problem.
DISCUSSION
Runway 10R-28L is primarily used by jet and turboprop aircraft and is the most critical runway for aircraft approaching the Airport. If oxidation of aggregate in the pavement is allowed to progress, particles could begin to flake and loosen from the pavement surface potentially causing damage to aircraft. A specialist from the Airport's consultant, AECOM, evaluated the runway and recommended that milling the existing pavement and applying a two-inch asphalt lift with proper mix should alleviate the rust issue. It was determined there are no sealants or other chemical products on the market that can successfully address the rust issue as an alternative to removing...
