Building Materials 10 Testing Methods page 72 14. AGGREGATES Aggregate is a collective term for the mineral materials such as sand, gravel and crushed stone that are used with a binding medium (such as water, bitumen, portland cement, lime, etc.) to form compound materials (such as asphalt concrete and portland cement concrete).
Different methods apply to different classes of aggregates, says Daniel Some, PhD, director of marketing and principal scientist at Wyatt Technology Corporation, and these classes include reversible vs. irreversible aggregates and small (or soluble) vs. large (or insoluble) aggregates.

Ceramic Processing. Some of the most common forming methods for ceramics include extrusion, slip casting, pressing, tape casting and injection molding. After the particles are formed, these "green" ceramics undergo a heattreatment (called firing or sintering) to produce a rigid, finished product.
The last process of paving is compaction. This process is highly influenced by major mix proportion; (1) asphalt content: aggregate size, shape texture and distribution gradation; (2) filler content, and; (3) mix temperature. Appropriate rollers and rolling methods should be used in accordance with these proportion.
