Asphalt Aggregate Gradation and Size Testing with ...

Gradation testing, also called sieve analysis, is a fairly basic yet essential test that measures the gradation (or distribution of aggregate particles, by size, within a given sample) to determine whether it’s compliant with design, production control requirements, and verification specifications.
