When should cores be assessed for quality after extraction?

Assessing cores for quality immediately after extraction is essential because it allows for the accurate evaluation of important properties such as density, moisture content, and voids. Timely assessment ensures that results reflect the material's condition right after compaction, which is crucial for determining whether the asphalt pavement meets specifications and quality standards. Immediate quality assessment enhances the ability to make necessary adjustments to the paving process if defects or non-compliance issues are found.

Delaying the assessment can introduce variables such as temperature changes and moisture loss, which can significantly affect the measurements and interpretation of the core's properties. Therefore, immediate evaluation is critical for maintaining quality control throughout the paving process and ensuring that the final pavement meets the desired performance criteria.
