Montana Moves to Volumetric Acceptance for Superpave

The article focuses on the Montana Department of Transportation's move to exclusively use, for Superpave mixes, volumetric acceptance criteria for improved hot mix asphalt (HMA) quality. The move toward volumetric acceptance criteria use in Montana began in 2000 after years of data review showed that "...with adequate incentives, [it] would level the playing field and allow quality to compete with quantity." Four criteria form the basis of Superpave mix acceptance: dust/binder ratio, voids filled with asphalt, voids in the mineral aggregate, and air voids. The authors conclude that one observable benefit over a three year period has been intense HMA producer focus on mix quality. Application on US Highway 93 in Montana is discussed.
