• Abstract:
  Research in the area of Superpave mix design has resulted in expansion of the ; nominal maximum aggregate size (NMAS) mix designs available and has ; established the relationship between NMAS and pavement performance. The ; NMAS mixes evaluated by the researchers ranged from 4.75 to 37.5 mm. Current ; Wisconsin Department of Transportation (WisDOT) specifications restrict the NMAS of ; the standard pavement design structure to 12.5 mm in the upper layer over a 19.0 mm lower ; layer, a practice that limits both the products available to designers/contractors and the ; flexibility to specify NMAS based on intended application. Recent advances in mix design ; at a national level present an opportunity for WisDOT to promote the use of a wider range ; of mix types through development of application guidelines for mixes of different NMAS.
