  • Abstract:
    This report analyzes the quality control/quality assurance (QC/QA) data for hot mix asphalt (HMA) using ; voids acceptance as the testing criteria awarded in the years 2000 through 2010. Analysis of the overall ; performance of the projects is accomplished by reviewing the Calculated Pay Factor Composite (CPFC) and ; Incentive/Disincentive Payments (I/DP). Analysis of each of the elements: asphalt content, voids in mineral ; aggregate (VMA), air voids, mat density, and joint density is presented in tables, figures, and reports. Various ; data groupings are used to evaluate the data including: year, region, and grading. ; The specification and the projects are performing reasonably well. The results for the data show that quality ; of the projects is remaining fairly consistent. No definite upward or downward trends can be seen in the data. ; Over the eleven-year time period more projects have received incentive payments than disincentive ; payments. The average CPFC over the eleven years evaluation is 1.00569. The quality levels in the ; individual elements are at relatively high levels. The VMA and mat density elements show the best results ; being above 93 percent within the specification limits. The asphalt content and air voids elements are at ; approximately 90 percent. The joint density pay factor is under 1.0 but is expected to rise as contractors gain ; experience in this area.
