| 摘要： | 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. |
