What is the minimum number of cores required, even if the lot is terminated?

In the context of asphalt paving and the requirements for core sampling, the minimum number of cores that must be taken, even if the lot is terminated, is three. This requirement is established to ensure that there is sufficient data for assessing the quality and characteristics of the asphalt pavement.

Coring is a critical part of quality control and ensures that the asphalt has been compacted properly and meets specified design criteria. By requiring a minimum of three cores, it allows for a more comprehensive evaluation and can account for variability in the pavement. Taking just one or two cores may not provide a reliable representation of the entire lot, thus increasing the risk of poor quality that might not be immediately apparent.

In summary, three cores provide a necessary level of data to make more informed decisions about the lot's quality, even in a situation where the lot is terminated. This approach aligns with quality assurance practices in construction and material testing, ensuring that adequate information is available for analysis and resulting decisions.
