This research examines a realistic approach for bituminous mix design for asphalt stabilized base courses. It concludes that the Air Force should continue using the Marshall Test Method for bituminous mixture design, but that current requirements for percent air voids in the mixture and percent voids filled with bitumen are too restrictive. It further concludes that test temperatures should be reduced from 140F for base course mixture design.
