• Abstract:
  Some asphalt pavement does not last as long as it should. Every year, a significant amount of money is spent by the state on ; repairing and maintaining pavement, which raises the question: Are we getting the mix design we need? Since hot mix asphalt (HMA) is ; the main paving material in Alaska, it is critical to understand how the quality of this material is assured. Often, a properly lab-designed ; HMA is used in the field on a given project and performs in a substandard manner. Variability is inevitable during construction. ; Two projects were selected for the study. Pertinent data from ADOT&PF and from contractors at lab/design and construction ; were obtained, including general information regarding the paving projects, details of the materials and JMF being used in the ; construction, quality control testing data from contractors, and acceptance testing results from the agency.
