Criteria for Asphalt-Rubber Concrete in Civil Airport Pavements: Mixture Design.
Abstract
A mixture design procedure is developed to allow the use of asphalt-rubber binders in concrete for flexible airport pavement. The asphalt-rubber is produced by reacting asphalt with ground, scrap tire rubber to produce the binder for the asphalt-rubber concrete. The report includes procedures for laboratory preparation of asphalt-rubber binders using an equipment setup that was found by researchers to produce laboratory binders with similar properties to field processes. The rubber-asphalt concrete mixture design procedure includes adjustments to the aggregate gradation to permit space for the rubber particles in the asphalt-rubber binder as well as suggested mixing and compaction temperatures, and compaction efforts. While the procedure has been used in the laboratory to successfully produce asphalt-rubber concrete mixtures, it should be evaluated in the field to ensure that consistent results can be achieved in a production environments.
