Is the assessment of quality characteristics of a lot based on multiple sublots?

The assessment of quality characteristics of a lot based on multiple sublots is indeed true. This approach is essential for ensuring that the overall quality of the hot mix asphalt (HMA) being produced meets the required specifications.

Quality assessment through multiple sublots allows for a more comprehensive evaluation of the material's properties. By dividing a large lot into smaller sublots, inspectors can analyze a representative sample of the material, helping to identify variations in quality that might occur across the entire lot. This sampling strategy minimizes the risk of accepting a lot with substandard quality and provides statistical validity to the quality control process.

Additionally, it reinforces the principle of statistical sampling in quality assurance, where larger and more diverse datasets lead to more reliable conclusions about the material's quality. Hence, assessing quality characteristics using multiple sublots is a fundamental practice in asphalt quality control.
