  Chapter 2 Asphalt and Asphalt Paving Materials

  Processed Aggregates When natural pit or bankrun aggregate has been crushed and screened to make it suitable for Asphalt Concrete pavements, it is consider ed a processed aggregate. Crushing typically improves the particle shape by making the rounded particles more angular. Crushing also improves the size distribution and range.
