Volumetric Requirements for Superpave Mix Design

mahyarov · 10-24-2012, 06:07 AM

This report presents the findings of two coordinated research projects that investigated whether changes to the recommended Superpave mix design criteria for voids in mineral aggregate, voids filled with asphalt, and air voids content might further enhance the performance and durability of hot mix asphalt. Its main finding is that, based on an evaluation of the performance properties of hot mix asphalt, major revisions to these volumetric criteria are not needed, although some refinements are possible. The report will be of particular interest to materials engineers in state highway agencies, as well as to materials suppliers and paving contractor personnel responsible for the specification and production of hot mix asphalt.
