Evaluation of Gap-Graded Asphalt Concrete Mixtures. Part II. Statistical Design and Analysis Part
The report presents the results of a comparative laboratory study between well- and gap-graded aggregates used in asphalt concrete paving mixtures. A total of 424 batches of asphalt concrete mixtures and 3,960 Marshall and Hveem specimens were examined. The main thrust of the statistical analysis conducted in this experiment was in the calibration study and in Part I of the experiment. In the former study, the compaction procedure between the Iowa State University Lab and the Iowa Highway Commission Lab was calibrated. By an analysis of the errors associated with the measurements the researchers were able to separate the 'preparation' and 'determination' errors for both laboratories as well as develop the calibration curve which describes the relationship between the compaction procedures at the two labs.
