TIME OF SAMPLING STRATEGIES FOR ASPHALT PAVEMENT QUALITY ASSURANCE
The cost of quality assurance programs in asphalt road construction is high partly due to the need for daily testing. This paper demonstrates the methodology used to investigate the timing of sampling and its effect on a quality assurance program. 14 lots over 2 highway paving projects were tested twice: during construction on a daily basis, and after construction was completed. Three quality measures were compared; namely, asphalt content, degree of compaction, and aggregate gradation. The test data during construction was obtained from 2 sources: the consultant's quality assurance, and the contractor's quality control. One-way ANOVA tests and T-tests were used to compare the means. In addition, the mathematical difference between the means was reviewed to understand how the time of sampling might affect contractor payment adjustments.
