    • Development of guidelines for PG binder selection for Wisconsin 

      Bahia, Hussain; Nam, Kitae; Delgadillo, Rodrigo (Wisconsin Highway Research Program, 2004-12)
      In 1997, the Wisconsin DOT made the transition to use PG binders in place of the Penetration and Viscosity graded asphalts that had been historically used. The decision at that time to specify the PG 58-28 as the standard ...
    • The effect of fine aggregate angularity, asphalt content and performance graded asphalts on hot mix asphalt performance 

      Stakston, Anthony; Bahia, Hussain (Wisconsin Highway Research Program, 2003-10)
      The Wisconsin Department of Transportation (WisDOT) has implemented the Superpave recommendations in the 2000 Supplemental Specifications. This research was directed towards better understanding of the influence of ...
    • Effect of pavement thickness on Superpave mix permeability and density 

      Bahia, Hussain; Russell, Jeffrey; Kanitpong, Kunnawee (Wisconsin Highway Research Program, 2005-04)
      This research study was conducted to determine the influence of maximum aggregate size, lift thickness, and aggregate source on the density and permeability of asphalt mixtures designed according to the Superpave criteria. ...
    • Field validation of Wisconsin modified binder selection guidelines 

      Bahia, Hussain; Motamed, Arash; Delgadillo, Rodrigo (Wisconsin Highway Research Program, 2007-06)
      In June 2005, a report with Modified Binder Selection Guidelines for Wisconsin was finished under the sponsorship of the Wisconsin Highway Research Program. The report name is Development of Guidelines for PG Binder Selection ...
    • Minimum pavement lift thickness for Superpave mixtures 

      Paye, Barry; Bahia, Hussain (Wisconsin Highway Research Program, 2001-12)
      The purpose of this study was to look at the effect of lift thickness as it relates to the density of Superpave Hot Mix Asphalts. The study consisted of two phases: (1) a laboratory study and (2) a field study. In the ...
    • Using gyratory compactor to measure mechanical stability of asphalt mixtures 

      Mahmoud, Ahmed Fatin Faheem; Bahia, Hussain (Wisconsin Highway Research Program, 2004-10)
      In this study several asphalt mixtures were produced using four different aggregate sources, different asphalt contents, and different aggregate gradations. Every mixture was compacted using the Superpave gyratory compactor ...
