Criteria for Coal Tar Seal Coats on Airport Pavements. Volume II Laboratory and Field Studies.

摘要

Because coal tars are resistant to gasoline and jet fuel, they have been used for many years as a protective coating on asphalt pavements for airport parking areas, ramps, taxiways and runways. Applications include both coal tar emulsions and rubberized coal tar emulsions, applied with sand to provide skid resistance and stability to the seal costs. Volume II of the report includes the results of an experimental Laboratory and field investigation conducted at the University of Nevada at Reno. The focus on the University program was to develop test procedures that would measure workability, scuff, adhesion and fuel resistance properties of coal tar emulsion seal coats. This program developed a method for designing seal coat formulations test procedures that could be used for quality assurance purposes. Volume II includes the test data generated in the study, including measurements made on field sections. (aw)
