Aggregate Grading vs. Gradation. You might hear the terms "aggregate grading" and "gradation" used interchangeably, but they actually refer to slightly different concepts. Gradation is the distribution of particle sizes within the aggregate, while grading is the classification of that aggregate into specific categories based on size.
