What must be included in the aggregate identification according to DOT requirements?

  1. Approved pit number and aggregate grade

  2. Source location and delivery date

  3. Weight and volume of aggregates

  4. Type of machinery used for sourcing

The correct answer is: Approved pit number and aggregate grade

The requirement for aggregate identification according to DOT specifications emphasizes the importance of tracking and verifying the quality of materials used in concrete production. Including the approved pit number ensures that the aggregate comes from a source that has met the necessary standards for quality control. The aggregate grade reflects the specific classification of the material, which is critical for ensuring that the properties of the concrete can meet design and performance criteria. Having this information is essential for quality assurance and compliance with project specifications. This traceability helps in evaluating the consistency and reliability of the concrete mix design solution. The other options, while they provide valuable information, do not encompass the main elements that the DOT specifically requires for aggregate identification.
