EVALUATING THE IMPACT OF QC/QA PROGRAMS ON ASPHALT MIXTURE VARIABILITY

The promise of using a quality control/quality assurance (QC/QA) specification for construction of asphalt pavements is that a less variable hot mix asphalt (HMA) will be produced with constant control throughout production and placement operations. This reduction in variability decreases the cost of the pavement over time through better performance and longer service life. Implementing QC/QA specification also increases cost. This cost is associated with the increased amount of testing required by the contractor. Due to the recent implementation, the benefits of using QC/QA specification have yet to be fully determined. The main objective of this research is to evaluate the effectiveness of the QC/QA specification in decreasing HMA variability in an effort to measure the impact of using QC/QA specifications.
