Development of Design Gyration Levels for Airfield Asphalt Pavement
The objective of this paper is to provide guidance for adapting Superpave gyratory compactor (SGC) procedures to design airfield asphalt mixes (specifically to select the design asphalt content) with comparable properties to Item P-401 protocol. Three methods were used for selecting the SGC design compactive effort: (1) evaluate in-place density in the general manner used during development of the Marshall mix design airfield procedure; (2) compare specimen bulk specific gravities compacted with the Marshall hammer and SGC; and (3) test airfield mixes using confined repeated load permanent deformation testing to determine the binder content at which the mixtures become unstable. The result of this analysis was a gyration level related to tire pressure.
