3 Aggregate Properties

Aggregate particles have certain physical and chemical properties which make the aggregate acceptable or unacceptable for specific uses and conditions. The following are of concern to INDOT. PHYSICAL PROPERTIES The physical properties of aggregates are those that refer to the physical structure of the particles that make up the aggregate.
