When asphalt mixtures are produced in excess of 801 tons, what is the required testing frequency for extraction and grading?

The correct answer regarding the required testing frequency for extraction and grading when producing asphalt mixtures in excess of 801 tons is that a test should be conducted for every 300 tons. This testing frequency is established to ensure the quality and consistency of the asphalt mixtures being produced.

Testing every 300 tons allows for adequate monitoring of the asphalt's properties, which is crucial for ensuring performance in its intended application. It strikes a balance between frequency and practicality, reflecting an industry standard that helps maintain material quality without imposing excessive testing demands on production processes.

This frequency provides enough data points to identify trends in the material properties and allows for timely adjustments to be made to the production process if inconsistencies are detected.
