• Abstract:
  This report analyzes the Quality Control/Quality Assurance (QC/QA) data for hot mix asphalt using voids acceptance as ; the testing criteria for the years 2000 through 2004. Analysis of the overall quality of the HMA is accomplished by ; reviewing the Calculated Pay Factor Composite (CPFC) and Incentive/Disincentive Payments (I/DP). Analysis of each of ; the test elements: asphalt content, voids in mineral aggregate, 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, & grading. ; The specification and the projects are performing reasonably well. Over the five-year time period more projects have ; received incentive payments than disincentive payments. The average pay over the five years is 1.00848. The quality ; levels in the individual elements are at reasonable levels. Over the five-year time period the VMA element has the best ; quality levels with an average of 95.00. Mat density has the next best results with an average of 92.89. Air voids and ; percent asphalt are third and fourth with average quality levels of 90.41 and 89.86. Joint density testing has been a ; requirement beginning in 2003. The pay factor for this element is just under 1.0 but is expected to increase as ; contractors gain experience in this area.
