When INDOT designs a pavement project, the decision for QC/QA or non-QC/QA is made solely based on the quantity of pavement materials. However, the actual risk will vary depending on the severity of road conditions. The question is how to differentiate the quality testing efforts according to the severity of road conditions in order to balance required testing resources. We found that the number of commercial vehicles (CV) and heat index (HI: number of hot days/freezing index) can be used as criteria in classifying the road conditions. Using these two criteria, CV and HI, we classify the road sections into four classes and provide different testing guidelines for different classes.
