Criteria for Coal Tar Seal Coats on Airport Pavements. Volume 1. State of the Art

Abstract

Because coal tars are resistant to gasoline and jet fuel, they have been used for many years as a protective coating on asphalt pavement used for airport parking areas, ramps, taxiways and runways. Applications include both coal tar emulsions and rubberized coal tar emulsions, generally applied with sand added to provide skid resistance and stability to the seal coats. This report describes typical coal tar emulsion seal coat formulations and construction practices, and list major distress manifestations reported by agencies contacted in the first year of the study. Also described are the results of site visits to several airports where problems have been encountered, the results of limited laboratory test conducted by outside agencies, and the basic laboratory study being conducted as part of this research effort. Keywords: Coal tar emulsion seal coats; Pavement maintenance; Airport pavement surfacing.
