Carbon Plex H-25 Preservation Coating Installed at John Wayne Airport

$10,000 per minute penalty is all the motivation pavement preservation crew needs to complete night runway project

The runway reconstruction specifications included the requirement for protecting 68,000 square yards of runway shoulder and aprons with a protective coating - Carbon Plex H-25 by Ecostar Science & Technology was selected.

John Wayne Airport (JWA) in Los Angeles recently completed reconstruction of its primary runway.

Because the airport is in close proximity to a neighborhood, its usually closed between 11 p.m. and 6 a.m. This presented the challenge of developing and installing a protective coating that could be placed and achieve full cure within this time window, so heavy jet traffic could resume operations.

Ramsey Oil Inc., a division of All American Asphalt, would install the coating. Paul Snow, Ramsey's crew manager, was tasked with coordinating nighttime field test applications of coating alternatives; which were then evaluated by JWA representatives.

After considering many options provided through the All American management team, the head of procurement, John Todorovich, concurred with the JWA representatives that the product supplied by Ecostar Science & Technology Inc. was the best choice.

That product was Carbon Plex H-25 - manufactured under an Ecostar license by Delta Trading, Inc. of Bakersfield, CA.

The installation of the coating was scheduled for late December 2008 but 40 degree F nighttime temperatures left little margin for error. The Carbon Plex emulsion, which has exhibited the quality of fully curing down to that temperature, had only been tested at John Wayne at nighttime with 50 degree F temperatures. The job was pushed back to January 8-9.

Everyone was antsy to wrap up this project after the months of coating study, even if it meant going in the middle of the winter, at night. The weather report for those dates was for rising temperatures and clear skies, with possible 'Santa Anna' winds which would provide excellent drying conditions. Everyone felt comfortable with pulling off this last critical phase of the project.
