How Aggregate Size Affects Bulk Density

Bulk density describes the mass of aggregate that fills a unit volume, including the empty spaces between particles. Those void spaces remain because aggregate particles cannot be packed so tightly that every gap disappears. In practice, bulk refers to the total volume of both the particles and the spaces around them.

The bulk density of aggregates indicates the mass of aggregates within a unit volume, including the void spaces existing among them. It is generally expressed in pounds per cubic foot.

Aggregates that are compacted densely achieve a higher bulk density compared to aggregates that are compacted loosely.
